On 64 bit, subtracting two pointers produces a long result. On 32 bit, it's an int. Even though long _is_ 32 bits on a 32 bit systems, gcc warns about it because reasons.

Also, the warning being that "expects int, but type is wchar_t"... no, type
is not wchar_t. Type is probably long. Specify the ACTUAL TYPE, not the random
typedef alias for it. If the translated type _did_ match, there wouldn't
be a warning! (This is why c89 promoted all arguments to int, precisely
so this wasn't a problem.)
