egcs, does gcc fixincludes etc guarantee a stdlib.h exists?

	I considered doing that, but I wasn't completely sure defining
that macro unconditionally in libgcc2.c or frame.c was a good idea.  Are
we guaranteed that defining __USE_FIXED_PROTOTYPES__ is safe for all
platforms? (I don't know, I'm asking.) If it is safe, then why does the
wrapper exist at all? ... 

	I don't have strong feelings either way.  Whatever Jeff decides
is fine with me.
