Changed the type of a compiler variable that holds either integers or pointers.

Browse Source 
The change allows cc65 to be compiled on 64-bit Windows, without getting warnings.  That OS is actually 32 bits with 64-bit pointers.  Its pointers are "long long" instead of "long".  The change uses type-names that are configured for the actual pointer width.
