I wasn't particularly thinking of constants. Some people use long long as 
long as they can, and switch to mpz_t (sometimes dynamically) when numbers 
won't fit anymore. In that case, the arguments are typically as large as 
builtin types will allow.

_GMP_H_HAVE_FILE, _GMP_H_HAVE_OBSTACK, _GMP_H_HAVE_VA_LIST are already too 
many feature macros and you want to avoid introducing a fourth one? Ok, I 
can understand that policy.
