Looking back through the commits to llvm-gcc-4.2/trunk/gcc/config/i386/darwin.h,
I see a total backout of format related warnings in r56923 followed by the
reapplication of
r569065 with a fix (r56946)...

followed by a fixed that claims not to enable the formatting warnings by default
on
darwin (r57326)...

It would seem obvious that this last patch must not really be functional since
gfortran is being given this formatting flags by default. I think this may not
be obvious for the other compilers since they don't complain if these flags
are present like gfortran does...

Unless we need something like a F951_SPEC entry in darwin.h?

ps Geoff, do you have any opinions on what could be going wrong here?
