patch for OrangeC

[Simon Sobisch]

This goes to gmp-h.in and allows using GMP from OrangeC with libgmp 
previously built by gcc-mingw32.

Please consider it for addition (in general free compilers should be 
"better supported" than MSC, even if they are not that common - at least 
if it is easy like here).
