Currently in llvm-gcc 4.2 from llvm 2.4 and llvm svn, the
gcc/config/i386/darwin.h header is inappropriately setting CC1_SPEC to always
pass...

-Wformat -Wformat-security -Wno-format-extra-args -Wno-format-zero-length
-Wno-nonnull 

This causes the llvm-gfortran compiler to spew warning messages of the form...

f951: warning: command line option "-Wformat" is valid for C/C++/ObjC/ObjC++
but not for Fortran
f951: warning: command line option "-Wformat-security" is valid for
C/C++/ObjC/ObjC++ but not for Fortran
f951: warning: command line option "-Wno-format-extra-args" is valid for
C/C++/ObjC/ObjC++ but not for Fortran
f951: warning: command line option "-Wno-format-zero-length" is valid for
C/C++/ObjC/ObjC++ but not for Fortran
f951: warning: command line option "-Wno-nonnull" is valid for
C/C++/ObjC/ObjC++ but not for Fortran

when any fortran source is compiled. These should either be removed from the
definition of CC1_SPECS or recrafted to not be used in the case of compilers
like gfortran that don't grok them.
