	We cannot force the bootstrap compiler to be "xlc" because other
logic (e.g., alloca.o) depends on the compiler being "cc" or being GCC
providing builtin alloca.  (Although IBM's compiler does provide builtin
alloca, I never have been able to successfully bootstrap using that.)

	Is this __STDC__ problem new?  This was not a problem in the past.

	Why not simply force a definition of __STDC__ into xm-rs6000.h?
...with or without an #ifndef wrapper.
