	(mpz_mod_ui): Move up to main section, it's still documented.

    _AIX - gnu ansidecl.h asserts that all known AIX compilers are ANSI but
        don't always define __STDC__.
 
+   __DECC - current versions of DEC C (5.9 for instance) for alpha are ANSI,
+       but don't define __STDC__ in their default mode.  Don't know if old
+       versions might have been K&R, but let's not worry about that unless
+       someone is still using one.

    _mips - gnu ansidecl.h says the RISC/OS MIPS compiler is ANSI in SVR4
        mode, but doesn't define __STDC__.
