Stop VC++ from warning "'getenv' : inconsistent dll linkage.

dllexport assumed." when building with -DDEBUGGING by declaring
getenv() with the same __declspec as in Microsoft's <stdlib.h>.
MinGW/GCC is happy with that too, but Borland doesn't understand
_CRTIMP so don't bother for Borland since it doesn't warn anyway.
