Version 2.0.3 (29 March 2011)
=============================

2011-03-29: wsfulton
            [R] Apply patch #3239076 from Marie White fixing strings for R >= 2.7.0

2011-03-29: wsfulton
            [Tcl] Apply patch #3248280 from Christian Delbaere which adds better error messages when
            the incorrect number or type of arguments are passed to overloaded methods.

2011-03-29: wsfulton
            [Tcl] Apply patch #3224663 from Christian Delbaere.
            1. Fix when function returns a NULL value, a "NULL" command will be created in the Tcl interpreter
            and calling this command will cause a segmentation fault. 

            2. Previous implementation searches for class methods using a linear search causing performance issues
            in wrappers for classes with many member functions. The patch adds a method hash table to classes and
            changes method name lookup to use the hash table instead of doing a linear search.

2011-03-26: wsfulton
	    [C#, Java] SF bug #3195112 - fix wrapping of enums that are type char, for example:
              enum { X = 'X'; }

2011-03-21: vadz
	    Allow setting PCRE_CFLAGS and PCRE_LIBS during configuration to override the values returned by
	    pcre-config, e.g. to allow using a static version of PCRE library.

2011-03-17: wsfulton
	    [UTL] Add missing headers in generated STL wrappers to fix compilation with gcc-4.6.

2011-03-17: wsfulton
	    Fix regression introduced in swig-2.0.2 where filenames with spaces were not found
	    when used with %include and %import. Reported by Shane Liesegang.

2011-03-15: wsfulton
	    [UTL] Fix overloading when using const char[], problem reported by David Maxwell.
            Similarly for char[ANY] and const char[ANY].

2011-03-15: wsfulton
	    [C#] Apply patch #3212624 fixing std::map Keys property.

2011-03-14: olly
	    [PHP] Fix handling of overloaded methods/functions where some
	    return void and others don't - whether this worked or not depended
	    on the order they were encountered in (SF#3208299).
	
2011-03-13: klickverbot
            [D] Extended support for C++ namespaces (nspace feature).

2011-03-12: olly
	    [PHP] Fix sharing of type information between multiple SWIG-wrapped
	    modules (SF#3202463).

2011-03-09: wsfulton
	    [Python] Fix SF #3194294 - corner case bug when 'NULL' is used as the default value
            for a primitive type parameter in a method declaration.

2011-03-07: olly
	    [PHP] Don't use zend_error_noreturn() for cases where the function
	    returns void - now this issue can only matter if you have a function
	    or method which is directed and returns non-void.

2011-03-06: olly
	    [PHP] Add casts to the typemaps for long long and unsigned long
	    long to avoid issues when they are used with shorter types via
	    %apply.

2011-03-02: wsfulton
	    Templated smart pointers overloaded with both const and non const operator-> generated uncompilable
	    code when the pointee was a class with either public member variables or static methods.
	    Regression in 2.0.x reported as working in 1.3.40 by xantares on swig-user mailing list.

Version 2.0.2 (20 February 2011)
================================

2011-02-19: wsfulton
	    [PHP] Add missing INPUT, OUTPUT and INOUT typemaps in the typemaps.i library
            for primitive reference types as well as signed char * and bool *.

2011-02-19: olly
	    [PHP] Address bug in PHP on some platforms/architectures which
	    results in zend_error_noreturn() not being available using
	    SWIG_ZEND_ERROR_NORETURN which defaults to zend_error_noreturn but
	    can be overridden when building the module by passing
	    -DSWIG_ZEND_ERROR_NORETURN=zend_error to the compiler.  This may
	    result in compiler warnings, but should at least allow a module
	    to be built on those platforms/architectures (SF#3166423).

2011-02-18: wsfulton
            Fix #3184549 - vararg functions and function overloading when using the -fastdispatch option.

2011-02-18: olly
	    [PHP] An overloaded method which can return an object or a
	    primitive type no longer causes SWIG to segfault.  Reported by Paul
	    Colby in SF#3168531.

2011-02-18: olly
	    [PHP] Fix invalid erase during iteration of std::map in generated
	    director code.  Reported by Cory Bennett in SF#3175820.

2011-02-17: wsfulton
            Preprocessing now warns if extra tokens appear after #else and #end.

2011-02-16: wsfulton
            Fix #1653092 Preprocessor does not error out when #elif is missing an expression.
            This and other cases of missing preprocessor expressions now result in an error.

2011-02-14: wsfulton
            [Ocaml] Apply patch #3151788 from Joel Reymont. Brings Ocaml support up to date 
            (ver 3.11 and 3.12), including std::string.

2011-02-13: wsfulton
            [Ruby] Apply patch #3176274 from James Masters - typecheck typemap for time_t.

2011-02-13: wsfulton
            Apply patch #3171793 from szager - protected director methods failing when -fvirtual is used.

2011-02-13: wsfulton
            Fix #1927852 - #include directives don't preprocess the file passed to it. The fix is for
            #include with -importall or -includeall, %include and %import, for example:
              #define FILENAME "abc.h"
              %include FILENAME

2011-02-12: wsfulton
            Fix #1940536, overactive preprocessor which was expanding defined(...) outside of #if and #elif
            preprocessor directives.

2011-02-05: wsfulton
            [MzScheme] SF #2942899 Add user supplied documentation to help getting started with MzScheme.
            Update chapter name to MzScheme/Racket accounting for the rename of MzScheme to Racket.

2011-02-05: wsfulton
            [C#] SF #3085906 - Possible fix running test-suite on Mac OSX.

2011-02-05: wsfulton
            SF #3173367 Better information during configure about Boost prerequisite for running
            the test-suite.

2011-02-05: wsfulton
            SF #3127633 Fix infinite loop in recursive typedef resolution.

2011-02-04: wsfulton
            [R] SF #3168676 Fix %rename not working for member variables and methods.

2011-02-04: wsfulton
            [clisp] SF #3148200 Fix segfault parsing nested unions.

2011-02-01: wsfulton
            [C#] Directors - a call to a method being defined in the base class, not
            overridden in a subclass, but again overridden in a class derived from
            the first subclass was not being dispatched correctly to the most derived class.
            See director_alternating.i for an example.

2011-02-01: wsfulton
            [C#, Java] Any 'using' statements in the protected section of a class were previously
            ignored with director protected (dirprot) mode.

2011-01-30: wsfulton
            Fix overloading with const pointer reference (SWIGTYPE *const&) parameters for a
            number of scripting languages.

2011-01-17: wsfulton
            New warning for smart pointers if only some of the classes in the inheritance
            chain are marked as smart pointer, eg, %shared_ptr should be used for all classes
            in an inheritance hierarchy, so this new warning highlights code where this is
            not the case.

              example.i:12: Warning 520: Base class 'A' of 'B' is not similarly marked as a smart pointer.
              example.i:16: Warning 520: Derived class 'C' of 'B' is not similarly marked as a smart pointer.

2011-01-14: wsfulton
            Added some missing multi-argument typemaps: (char *STRING, size_t LENGTH) and 
            (char *STRING, int LENGTH). Documentation for this updated. Java patch from
            Volker Grabsch.

2011-01-11: iant
	    Require Go version 7077 or later.

2010-12-30: klickverbot
            [C#, D, Java] Check for collision of parameter names with target
            language keywords when generating the director glue code.
            
            The situation in which the generated could would previously be
            invalid is illustrated in the new 'director_keywords' test case.

2010-12-23: wsfulton
            [C#] Fix $csinput special variable not being expanded for csvarin typemaps
            when used for global variables. Reported by Vadim Zeitlin.

2010-12-14: wsfulton
            Fix $basemangle expansion in array typemaps. For example if type is int *[3],
            $basemangle expands to _p_int.

2010-12-07: iant
	    Check that we are using a sufficiently new version of the
	    6g or 8g Go compiler during configure time. If not, disable Go.
            Minimum version is now 6707.

	    *** POTENTIAL INCOMPATIBILITY ***

2010-12-06: wsfulton
            Fix #3127394 - use of network paths on Windows/MSys.

2010-11-18: klickverbot
	    [D] Added the D language module.

2010-11-12: vadz
	    Fix handling of multiple regex-using %renames attached to the same
	    declaration. For example, now

	      %rename("%(regex/^Set(.*)/put\\1/)s") "";
	      %rename("%(regex/^Get(.*)/get\\1/)s") "";

	    works as expected whereas before only the last anonymous rename was
	    taken into account.

2010-10-17: drjoe
	    [R] Fix failure in overloaded functions which was breaking
	    QuantLib-SWIG

2010-10-14: olly
	    [PHP] Allow compilation on non-conforming Microsoft C++ compilers
	    which don't accept: return function_returning_void();
	    Reported by Frank Vanden Berghen on the SWIG mailing list.

2010-10-12: wsfulton
            Fix unary scope operator (::) (global scope) regression introduced in 2.0.0, reported by
            Ben Walker. The mangled symbol names were incorrect, sometimes resulting in types being
            incorrectly treated as opaque types.

            Also fixes #2958781 and some other type problems due to better typedef resolution, eg 
            std::vector<T *>::value_type didn't resolve to T * when it should have. The mangled type
            was incorrectly SWIGTYPE_std__vectorT_Test_p_std__allocatorT_Test_p_t_t__value_type and now
            it is correctly SWIGTYPE_p_Test.

Version 2.0.1 (4 October 2010)
==============================

2010-10-03: wsfulton
            Apply patch #3066958 from Mikael Johansson to fix default smart pointer
            handling when the smart pointer contains both a const and non-const operator->.

2010-10-01: wsfulton
            Add -pcreversion option to display PCRE version information.

2010-10-01: olly
	    [Ruby] Avoid segfault when a method node has no parentNode
	    (SF#3034054).

2010-10-01: olly
	    [Python] Allow reinitialisation to work with an embedded Python
	    interpreter (patch from Jim Carroll in SF#3075178).

2010-09-28: wsfulton
            [C#] Apply patch from Tomas Dirvanauskas for std::map wrappers to avoid
            throwing exceptions with normal usage of iterators.

2010-09-27: olly
	    [Python] Improve error message given when a parameter of the wrong
	    type is passed to an overloaded method (SF#3027355).

2010-09-25: wsfulton
            Apply SF patch #3075150 - Java directors using static variables in
            named namespace.

2010-09-24: wsfulton
            More file and line error/warning reporting fixes where SWIG macros
            are used within {} braces (where the preprocessor expands macros),
            for example macros within %inline {...} and %fragment(...) {...}
            and nested structs.

2010-09-18: wsfulton
            More file and line error/warning reporting fixes for various inherited
            class problems.

2010-09-15: wsfulton
            A much improved debugging of SWIG source experience is now available and
            documented in the "Debugging SWIG" section in the Doc/Devel/internals.html
            file, including a swig.dbg support file for the gdb debugger.

2010-09-11: wsfulton
            Fix incorrect line number reporting in errors/warnings when a macro
            definition ends with '/' and it is not the end of a C comment.

2010-09-11: wsfulton
            Fix incorrect line number reporting in errors/warnings after parsing
            macro invocations with parameters given over more than one line.

2010-09-10: wsfulton
            Remove extraneous extra line in preprocessed output after including files
            which would sometimes lead to error/warning messages two lines after the
            end of the file.

2010-09-10: wsfulton
            Fix #2149523 - Incorrect line number reporting in errors after parsing macros
            containing C++ comments.

2010-09-08: olly
	    [PHP] Fix handling of OUTPUT typemaps (Patch from Ryan in SF#3058394).

2010-09-03: wsfulton
            Fix erroneous line numbers in error messages for macro expansions, for example,
            the error message now points to instantiation of the macro, ie the last line here:

              #define MACRO2(a, b) 

              #define MACRO1(NAME) MACRO2(NAME,2,3) 

              MACRO1(abc)

2010-09-02: wsfulton
            Fix line numbers in error and warning messages for preprocessor messages within
            %inline, for example:

              %inline %{
              #define FOOBAR 1
              #define FOOBAR "hi"
              %}

2010-09-02: wsfulton
            Fix line numbers in error and warning messages which were cumulatively one
            less than they should have been after parsing each %include/%import - bug
            introduced in swig-1.3.32. Also fix line numbers in error and warning messages
            when new line characters appear between the %include / %import statement and
            the filename.

2010-08-30: wsfulton
            Fix line number and file name reporting for some macro preprocessor warnings.
            The line number of the macro argument has been corrected and the line number
            of the start of the macro instead of one past the end of the macro is used.
            Some examples:
              file.h:11: Error: Illegal macro argument name '..'
              file.h:19: Error: Macro 'DUPLICATE' redefined,
              file.h:15: Error: previous definition of 'DUPLICATE'.
              file.h:25: Error: Variable-length macro argument must be last parameter
              file.h:32: Error: Illegal character in macro argument name
              file.i:37: Error: Macro 'SIT' expects 2 arguments

2010-08-26: wsfulton
            Fix __LINE__ and __FILE__ expansion reported by Camille Gillot. Mostly this
            did not work at all. Also fixes SF #2822822.

2010-08-17: wsfulton
            [Perl] Fix corner case marshalling of doubles - errno was not being correctly
            set before calling strtod - patch from Justin Vallon - SF Bug #3038936.

2010-08-17: wsfulton
            Fix make distclean when some of the more obscure languages are detected by
            configure - fixes from Torsten Landschoff.

2010-07-28: wsfulton
            Restore configuring out of source for the test-suite since it broke in 1.3.37.
            As previously, if running 'make check-test-suite' out of source, it needs to be
            done by invoking configure with a relative path. Invoking configure with an
            absolute path will not work. Running the full 'make check' still needs to be
            done in the source tree.

2010-07-16: wsfulton
            Fix wrapping of function pointers and member function pointers when the function
            returns by reference.

2010-07-13: vadz
            Removed support for the old experimental "rxspencer" encoder and
            "[not]rxsmatch" in %rename (see the 01/16/2006 entry). The new and
            officially supported "regex" encoder and "[not]regexmatch" checks
            should be used instead (see the two previous entries). Please
            replace "%(rxspencer:[pat][subst])s" with "%(regex:/pat/subst/)s"
            when upgrading. Notice that you will also need to replace the back-
            references of form "@1" with the more standard "\\1" and may need to
            adjust your regular expressions syntax as the new regex encoder uses
            Perl-compatible syntax and not (extended) POSIX syntax as the old one.

            *** POTENTIAL INCOMPATIBILITY ***

2010-07-13: vadz
            Add "regexmatch", "regextarget" and "notregexmatch" which can be
            used to apply %rename directives to the declarations matching the
            specified regular expression only. The first two can be used
            interchangeably, both of the %renames below do the same thing:

                %rename("$ignore", regexmatch$name="Old$") "";
                %rename("$ignore", regextarget=1) "Old$";

            (namely ignore the declarations having "Old" suffix).

            "notregexmatch" restricts the match to only the declarations which
            do not match the regular expression, e.g. here is how to rename to
            lower case versions all declarations except those consisting from
            capital letters only:

                %rename("$(lowercase)s", notregexmatch$name="^[A-Z]+$") "";

2010-07-13: vadz
            Add the new "regex" encoder that can be used in %rename, e.g.

                %rename("regex:/(\\w+)_(.*)/\\2/") "";

            to remove any alphabetical prefix from all identifiers. The syntax
            of the regular expressions is Perl-like and PCRE library
            (http://www.pcre.org/) is used to implement this feature but notice
            that backslashes need to be escaped as usual inside C strings.

            Original patch from Torsten Landschoff.

2010-07-08: wsfulton
            Fix #3024875 - shared_ptr of classes with non-public destructors. This also fixes
            the "unref" feature when used on classes with non-public destructors.

2010-06-17: ianlancetaylor
            [Go] Add the Go language module.

2010-06-10: wsfulton
            [Lua] Fix SWIG_lua_isnilstring multiply defined when using multiple
            modules and wrapping strings. Patch from 'Number Cruncher'.

2010-06-10: olly
	    [PHP] Fix directors to correctly call a method with has a
	    different name in PHP to C++ (we were always using the C++ name
	    in this case).

2010-06-03: wsfulton
            Fix uncompileable code when %rename results in two enum items
            with the same name. Reported by Vadim Zeitlin.

Version 2.0.0 (2 June 2010)
===========================

2010-06-02: wsfulton
            [C#] Fix SWIG_STD_VECTOR_ENHANCED macro used in std::vector to work with
            types containing commas, for example:

              SWIG_STD_VECTOR_ENHANCED(std::pair< double, std::string >)

2010-06-01: wsfulton
            Add in std_shared_ptr.i for wrapping std::shared_ptr. Requires the %shared_ptr
            macro like in the boost_shared_ptr.i library. std::tr1::shared_ptr can also be
            wrapped if the following macro is defined:

              #define SWIG_SHARED_PTR_SUBNAMESPACE tr1
              %include <std_shared_ptr.i>

            shared_ptr is also documented in Library.html now.

2010-05-27: wsfulton
            Add the ability for $typemap special variable macros to call other $typemap
            special variable macros, for example:

              %typemap(cstype) CC "CC"
              %typemap(cstype) BB "$typemap(cstype, CC)"
              %typemap(cstype) AA "$typemap(cstype, BB)"

	    [PHP] When using %throws or %catches, SWIG-generated PHP5 wrappers
	    now throw PHP Exception objects instead of giving a PHP error of
	    type E_ERROR.

	    This change shouldn't cause incompatibility issues, since you can't
	    set an error handler for E_ERROR, so previously PHP would just exit
	    which also happens for unhandled exceptions.  The benefit is you can
	    now catch them if you want to.

            A static constructor has been added to the intermediary class like this:

            If you had added your own custom static constructor to the intermediary class in
            the same way as above, you will have to modify your approach to use static variable
            initialization or define SWIG_CSHARP_NO_IMCLASS_STATIC_CONSTRUCTOR - See csharphead.swg.

2010-04-01: wsfulton
            Numerous subtle typemap matching rule fixes when using the default type. The typemap
            matching rules are to take a type and find the best default typemap (SWIGTYPE, SWIGTYPE* etc),
            then look for the next best match by reducing the chosen default type. The type deduction
            now follows C++ class template partial specialization matching rules.

            Below are the set of changes made showing the default type deduction
            along with the old reduced type and the new version of the reduced type:

                   SWIGTYPE const &[ANY]
              new: SWIGTYPE const &[]
              old: SWIGTYPE (&)[ANY]

                   SWIGTYPE *const [ANY]
              new: SWIGTYPE const [ANY]
              old: SWIGTYPE *[ANY]

                   SWIGTYPE const *const [ANY]
              new: SWIGTYPE *const [ANY]
              old: SWIGTYPE const *[ANY]

                   SWIGTYPE const *const &
              new: SWIGTYPE *const &
              old: SWIGTYPE const *&

                   SWIGTYPE *const *
              new: SWIGTYPE const *
              old: SWIGTYPE **

                   SWIGTYPE *const &
              new: SWIGTYPE const &
              old: SWIGTYPE *&

            Additionally, a const SWIGTYPE lookup is used now for any constant type. Some examples, where
            T is some reduced type, eg int, struct Foo:

                   T const
              new: SWIGTYPE const
              old: SWIGTYPE

                   T *const
              new: SWIGTYPE *const
              old: SWIGTYPE *

                   T const[]
              new: SWIGTYPE const[]
              old: SWIGTYPE[]

                   enum T const
              new: enum SWIGTYPE const
              old: enum SWIGTYPE

                   T (*const )[]
              new: SWIGTYPE (*const )[]
              old: SWIGTYPE (*)[]

            Reminder: the typemap matching rules can now be seen for any types being wrapped by using
            either the -debug-tmsearch or -debug-tmused options.

            In practice this leads to some subtle matching rule changes and the majority of users
            won't notice any changes, except in the prime area of motivation for this change: Improve
            STL containers of const pointers and passing const pointers by reference. This is fixed
            because many of the STL containers use a type 'T const&' as parameters and when T is 
            a const pointer, for example, 'K const*', then the full type is 'K const*const&'. This
            means that the 'SWIGTYPE *const&' typemaps now match when T is either a non-const or
            const pointer. Furthermore, some target languages incorrectly had 'SWIGTYPE *&' typemaps
            when these should have been 'SWIGTYPE *const&'. These have been corrected (Java, C#, Lua, PHP).

            These are needed in order for the nspace option to work without any other mods.
            The previous default of protected access can be restored using:

              SWIG_JAVABODY_METHODS(protected, protected, SWIGTYPE)

            [C#] Added the nspace feature for C#. Documentation for the nspace feature is now available.

2010-03-04: wsfulton
            Added the nspace feature. This adds some improved namespace support. Currently only Java
            is supported for target languages, where C++ namespaces are automatically translated into
            Java packages. The feature only applies to classes,struct,unions and enums declared within
            a namespace. Methods and variables declared in namespaces still effectively have their
            namespaces flattened. Example usage:

              %feature(nspace) Outer::Inner1::Color;
              %feature(nspace) Outer::Inner2::Color;

              namespace Outer {
                namespace Inner1 {
                  struct Color {
                    ...
                  };
                }
                namespace Inner2 {
                  struct Color {
                    ...
                  };
                }
              }

            For Java, the -package option is also required when using the nspace feature. Say
            we use -package com.myco, the two classes can then be accessed as follows from Java:

              com.myco.Outer.Inner1.Color and com.myco.Outer.Inner2.Color.

2009-11-18: wsfulton
            Fix #491476 - multiple declarations of nested structs, for example:

	    [php] Fix place where class prefix (as specified with -prefix)

2009-11-12: wsfulton
            Fix usage of nested template classes so that compileable code is generated - the nested
            template class is now treated like a normal nested classes, that is, as an opaque type
            unless the nestedworkaround feature is used.

2009-11-12: wsfulton
            Replace SWIGWARN_PARSE_NESTED_CLASS with SWIGWARN_PARSE_NAMED_NESTED_CLASS and
            SWIGWARN_PARSE_UNNAMED_NESTED_CLASS for named and unnamed nested classes respectively.

            Named nested class ignored warnings can now be suppressed by name using %warnfilter, eg:

              %warnfilter(SWIGWARN_PARSE_NAMED_NESTED_CLASS) Outer::Inner;

            but clearly unnamed nested classes cannot and the global suppression is still required, eg:

              #pragma SWIG nowarn=SWIGWARN_PARSE_UNNAMED_NESTED_CLASS

2009-11-11: wsfulton
            Added the nestedworkaround feature as a way to use the full functionality of a nested class 
            (C++ mode only). It removes the nested class from SWIG's type information so it is as if SWIG
            had never parsed the nested class. The documented nested class workarounds using a global
            fake class stopped working when SWIG treated the nested class as an opaque pointer, and
            this feature reverts this behaviour. The documentation has been updated with details of how
            to use and implement it, see the "Nested classes" section in SWIGPlus.html.

2009-11-11: wsfulton
            There were a number of C++ cases where nested classes/structs/unions were being handled
            as if C code was being parsed which would oftentimes lead to uncompileable code as an
            attempt was made to wrap the nested structs like it is documented for C code. Now all
            nested structs/classes/unions are ignored in C++ mode, as was always documented. However,
            there is an improvement as usage of nested structs/classes/unions is now always treated
            as an opaque type by default, resulting in generated code that should always compile.

2009-11-08: wsfulton
            Fix inconsistency for nested structs/unions/classes. Uncompileable code was being
            generated when inner struct and union declarations were used as types within the
            inner struct. The inner struct/union is now treated as a forward declaration making the
            behaviour the same as an inner class. (C++ code), eg:

              struct Outer {
                struct InnerStruct { int x; };
                InnerStruct* getInnerStruct();

              using namespace ::AA;

            and bug #1816802 - SwigValueWrapper should be used:

              struct CC {
                CC(int); // no default constructor
              };
              ::CC x();

            and in template parameter specializations:

              struct S {};
              template <typename T> struct X { void a() {}; };
              template <> struct X<S> { void b() {}; };
              %template(MyTConcrete) X< ::S >;

            plus probably some other corner case usage of ::.

2009-10-20: wsfulton
	    Fixed previously fairly poor template partial specialization and explicit 
            specialization support. Numerous bugs in this area have been fixed including:

            - Template argument deduction implemented for template type arguments, eg this now
              works:
                template<typename T> class X      {};
                template<typename T> class X<T *> {};
                %template(X1) X<const int *>; // Chooses T * specialization

              and more complex cases with multiple parameters and a mix of template argument
              deduction and explicitly specialised parameters, eg:
                template <typename T1, typename T2> struct TwoParm               { void a() {} };
                template <typename T1>              struct TwoParm<T1 *, int *>  { void e() {} };
                %template(E) TwoParm<int **, int *>;

            Note that the primary template must now be in scope, like in C++, when
            an explicit or partial specialization is instantiated with %template.

              && || == != < > <= >= (Actually the last 4 are still broken). For example:

              #define A 10
              #define B 10
              #define A_EQ_B  A == B // now wrapped as type bool for C++

                      test3(n)

            This fix affected SWIG_AsCharPtrAndSize() so you cannot call this function with
            a null alloc and non-null cptr argument in Python 3, otherwise a runtime error
            will be raised.

	    [C#] std::vector<T> wrapper improvements for .NET 2 and also providing the
	    necessary machinery to use the std::vector<T> wrappers with more advanced features such
	    as LINQ - the C# proxy class now derives from IEnumerable<>. The default is now to 
	    generate code requiring .NET 2 as a minimum, although the C# code can be compiled 
	    for .NET 1 by defining the SWIG_DOTNET_1 C# preprocessor constant. See the 
	    std_vector.i file for more details.

            [Python] Some fixes for Python 3.0.1 and higher support. In 3.0.1, the C API function
            PyObject_Compare is removed, so PyObject_RichCompareBool is used for replacement.
            Struct initilization of SwigPyObject and SwigPyObject_as_number changed to reflect
            the drop of tp_compare and nb_long.

            [Python] Fix SF#2583160. Now the importer in Python shadow wrapper take care of the
            case that module already imported at other place.

2009-02-28: bhy
            [Python] Fix SF#2637352. Move struct declaration of SWIG_module in pyinit.swg before
            the method calls, since some C compiler don't allow declaration in middle of function
            body.

	    Fix SF #2605955: -co option which broke in 1.3.37. 

2009-02-20: wsfulton
	    New %insert("begin") section added. Also can be used as %begin. This is a new
	    code section reserved entirely for users and the code within the section is generated
	    at the top of the C/C++ wrapper file and so provides a means to put custom code
	    into the wrapper file before anything else that SWIG generates.

	    'make clean-test-suite' will now run clean on ALL languages. Previously it only
	    ran the correctly configured languages. This way it is now possible to clean up
	    properly after running 'make partialcheck-test-suite'.

2009-02-14: wsfulton
	    Extend attribute library support for structs/classes and the accessor functions use
	    pass/return by value semantics. Two new macros are available and usage is identical
	    to %attribute. These are %attributeval for structs/classes and %attributestring for
	    string classes, like std::string. See attribute.swg for more details.

2009-02-13: wsfulton
	    Add support for %extend and memberin typemaps. Previously the memberin typemaps were
	    ignored for member variables within a %extend block.

2009-02-12: wsfulton
	    Remove unnecessary temporary variable when wrapping return values that are references. 
	    Example of generated code for wrapping:

	      struct XYZ {
		std::string& refReturn();
	      };

	    used to be:

              std::string *result = 0 ;
              ...
              {
                std::string &_result_ref = (arg1)->refReturn();
                result = (std::string *) &_result_ref;
              }

	     Now it is:

              std::string *result = 0 ;
              ...
              result = (std::string *) &(arg1)->refReturn();

2008-12-30: wsfulton
	    Bug #2430756. All the languages now define a macro in the generated C/C++
	    wrapper file indicating which language is being wrapped. The macro name is the
	    same as those defined when SWIG is run, eg SWIGJAVA, SWIGOCTAVE, SWIGCSHARP etc
	    and are listed in the "Conditional Compilation" section in the documentation.

	    code with either a C/C++ compiler or SWIG. Documentation is in CCache.html
	    or the installed ccache-swig man page.
