Here is the updated version which also does the same
thing for MATH_LIBRARY which is needed for g++ and gfortran
as they implicitly use the C99 math functions.  I will
also look into how to stop libstdc++'s needing libmath
on Darwin 7.x.

OK? Bootstrapped on powerpc-apple-darwin7.3.0 with no regressions.
Also bootstrapped on powerpc-apple-darwin6.8 with no regressions either.
I bootstrapped the tree-ssa so that I could see if no target independent
failures on gfortran and I do not.

ChangeLog:
	* config/darwin7.h: New file.
	* config.gcc (*-*-darwin*): Add darwin7.h if the
	version is greater than 6.
	* config/darwin.h (TARGET_C99_FUNCTIONS): Define.
	(MATH_LIBRARY): Wrap in ifdefs.
