// -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
// -Wreserved-id-macro - causes a lot of problems with xctest framework.
