use int instead of long for ptrdiff_t on all 32-bit archs
this is needed to match the underlying "ABI" standards. it's not really an ABI issue since the binary representations are the same, but having the wrong type can lead to errors when the type arising from a difference-of-pointers expression does not match the defined type of ptrdiff_t. most of the problems affect C++, not C.
