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