// NOTE: as of Xcode 3.1, for iPhone development, the two SDKs you can match are:
//   SDK_NAME iphoneos2.0
//   SDK_NAME iphoneos2.1
//   SDK_NAME iphonesimulator2.0
//   SDK_NAME iphonesimulator2.1
// for Mac OS developement, the values are:
//   SDK_NAME macosx10.4
//   SDK_NAME macosx10.5
//   SDK_NAME macosx10.6

// Pick up the Xcode default settings for ARCHS.  Keep the historical behavior
// of providing overrides for the older SDKs so existing apps are less likely

// Strictest warning policy that we can do
// Options intentionally turned off
// http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
// -Wsystem-headers - since we can't fix them we are going to assume they're ok
// -Wtraditional - we are compiling with c99, so we don't care about trad
// -Wdeclaration-after-statement - we are compiling with c99 which allows this
// -Wpadded - lots of structures will get padded, so although this warning may
//            be useful to show us badly padded structures, it causes to many
//            warnings to be on generally.
// -Wunreachable-code - several macros use the do {} while (0) which always
//                      flags this. e.g. all the ST... macros for unittesting
// -Wredundant-decls - we sometimes use redundant decls to add an attribute
//                     to a function/method (i.e.
// -Waggregate-return - NSPoint, NSRect etc are often returned as aggregates
// -Wshorten-64-to-32 - this is defined in the 64 bit build settings
// -Wcast-qual - Would love to turn this on, but causes issues when converting
//               CFTypes to NSTypes and also has issues with some external
//               libraries (notably zlib)
// -Wundef - we conditionalize on TARGET_OS_IPHONE which is only defined
//           in the iPhoneSDK making us unable to turn this warning on.
// -Wstrict-prototypes - breaks the GTM_METHOD_CHECK macro
// -Wcast-align - causes a whole pile of problems buildng with iPhoneSDK

// Objective C warnings
// http://gcc.gnu.org/onlinedocs/gcc/Objective_002dC-and-Objective_002dC_002b_002b-Dialect-Options.html
// -Wassign-intercept - this really is more informational than a warning.
// -Wselector - the system headers define lots of methods with the same selector
//              rendering this mostly useless to us
// -Wstrict-selector-match - the system headers define lots of methods with the
//                           same selector rendering this mostly useless to us
