I don't know much about GMP code, but wouldn't it make sense to use
these C99 features?  If a platform does not have them defined, you can
define them yourself to something suitable with an Autoconf script or something.

On Windows, PRIdMAX needs to be "I64d" (mingw inttypes.h does this,
Microsoft headers probably don't).  With msvc, uintmax_t would be
`unsigned __int64', and with gcc it would be `unsigned long long'.
