From
`/System/Library/Frameworks/CoreFoundation.framework/Headers/CFString.h`
on `bsd` (and presumably other OS X systems):
{{{
#if defined(__GNUC__) && (__GNUC__*10+__GNUC_MINOR__ >= 42) &&
!defined(__INTEL_COMPILER) && (TARGET_OS_MAC || TARGET_OS_EMBEDDED)
#define CF_FORMAT_FUNCTION(F,A) __attribute__((format(CFString, F, A)))
#define CF_FORMAT_ARGUMENT(A) __attribute__((format_arg(A)))
#else
#define CF_FORMAT_FUNCTION(F,A)
#define CF_FORMAT_ARGUMENT(A)
#endif
}}}
Here Apple is assuming that gcc >= 4.2 will properly understand
`_attribute__((format_arg()))` but this isn't true. Obviously this works
with XCode's C compiler, not with GCC. A stupid workaround is to define
`__INTEL_COMPILER` when compiling Python on OS X.
