with Borland,
you use IMPLIB.EXE, and for MSVC, you use IMPDEF and LIB) that take a dll
and output a '.lib'.
Then, you add the .lib to your project and #include <gmp.h> (or "gmp.h") in
your source code... After that, there's no need to mess-up with the
specificities of calls to dll, it's all done in gmp.h. Just ensure that the
dll itself (called LIBGMP-3.DLL) is in your program directory.
