gmp.h uses undefined preprocessor symbol

[Simon Sobisch]

The following bug exists since at least GMP 4.3 and still persists:

gmp-h.in defines _GMP_DECLSPEC_EXPORT / _GMP_DECLSPEC_IMPORT for
different systems and use it later.

The problem: it does not define it to something for unknown environments.

The attached patch defines them empty when the compiler is not known and
adds the working definition for the OrangeC compiler.

[Note: the patch used the old format, ORANGEC understands both
´__dllexport__´ and ´dllexport´ so it may be added to the GCC-define]
