New description:
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
}}}
Later on, Apple is using this in an improper way. From
`/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBundle.h`:
{{{
CF_EXPORT
CFStringRef CFBundleCopyLocalizedString(CFBundleRef bundle, CFStringRef
key, CFStringRef value, CFStringRef tableName) CF_FORMAT_ARGUMENT(2);
}}}
The problem here is that some versions of GCC do not recognize
"CFStringRef" as a string type (IMHO GCC is right, this isn't a string
type). Disabling the "format_arg()" attribute with `'-Dformat_arg(x)='`
works.
This causes failures for Python and R.
