win32 _decl problems

[delta trinity]

Hello Fredrick

Well, I think it's easier to simply use the gmp.h functions.  Visual Studio 
should automatically detect (from the .lib) that the calls are cdecl.

If you have already included 'gmp.h', you may get an error if you try to 
re-define the functions.
