... for C. For C++, since stdio is always included, it would seem 
consistent to also include stdarg (although that would be a different 
patch).

It looks like an old patch against some old version of gmp that was ported 
to gmp-4.3 without checking that cstdio is already included at the top of 
the file.

It has been supported for quite a long time for Sun. Forte 6U2 is I think 
the only version that doesn't understand this syntax and is not completely 
dead. Anyway, __SUNPRO_C>=0x540 should be safe, if I read the doc 
correctly.
