--- Comment #3 from Iain Sandoe <iains at gcc dot gnu.org> 2010-11-06 10:57:02 UTC ---
NOTE:

To close this on the 4.5 branch will require back-porting
r165820
r165821
(to provide the CFString implementation and testsuite)

r166398/166399 (166399 corrects an unintended commit).
(to provide the format check).

But this should be fixed on trunk now - leaving it open pending a decision on
the back-port.

I'm fine with a backport, just ask Joseph to weigh in.

 Closing because scale of backport makes approval unlikely.

------- Comment #1 from howarth at nitro dot med dot uc dot edu  2010-07-18 18:48 -------
Note that this issue only occurs in darwin10 because of the introduction of ...

#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

in /System/Library/Frameworks/CoreFoundation.framework/Headers/CFString.h which
makes the assumption that all gcc greater than gcc 4.2 supports the CFString
format. I had suggested in radar 6845745 that this be fixed in darwin10 with...

but I don't think this will ever happen for darwin10. Mike has suggested that
better fix is to add port over the support for the CFString format.
