/* FIXME: PHP5 OO wrapping TODO list:
 *
 * Short term (ideally before 1.3.30 is released):
 *
 * Sort out auto-renaming of method and class names which are reserved
 *   words (e.g. empty, clone, exception, etc.) vs -php4/-php5 in some
 *   sane way.
 *
 * Sort out wrapping of static member variables in OO PHP5 (which first may
 *   mean we need to sort them out for PHP4!)
 *
 * Medium term:
 *
 * Handle default parameters on overloaded methods in PHP where possible.
 *   (Mostly done - just need to handle cases of overloaded methods with
 *   default parameters...)
 *   This is an optimisation - we could handle this case using a PHP
 *   default value, but currently we treat it as we would for a default
 *   value which is a compound C++ expression (i.e. as if we had a
 *   a method with two overloaded forms instead of a single method with
 *   a default parameter value).
 *
 * Create __isset method for PHP 5.1 and later (we can probably just
 *   always generate as PHP 5.0 should just ignore it).
 *
 * Long term:
 *
 * Option to generate code to work with PHP4 instead ("public $_cPtr;" ->
 *   "var $_cPtr;", "abstract" -> "", no static class functions - but making
 *   these changes gives a segfault with make check...)
 * Sort out locale-dependent behaviour of strtod() - it's harmless unless
 *   SWIG ever sets the locale and DOH/base.c calls atof, so we're probably
 *   OK currently at least.
 */

/*
 * TODO: Replace remaining stderr messages with Swig_error or Swig_warning
 * (may need to add more WARN_PHP4_xxx codes...)
