The C99 standard has introduced the following datatypes:

intptr_t and uintptr_t

these are integral types capable to store integer or pointer.

All newer and many pre C99 compilers (as sunproc or xlc) support this datatype.

the Microsoft compiler cl.exe 12.00 (Visual Studio 6) has an INT_PTR and
UINT_PTR types instead.
cl.exe 13.00 supports both intptr_t and uintptr_t.

Why not use these types in places where GPOINTER_TO_INT is heavily used?
