You added an extra prototype for mpz_set_str on top of what's in
gmp.h?  The difference between the two is likely to be provoking the
error.

You're probably best off leaving the compiler in the default cdecl
mode.  If you really want stdcall or fastcall on your own functions
you can give it explicitly.
