How should ObjC encode 'long'?

Currently, ObjC encodes 'long' as 'l' (and 'unsigned long' as 'L'), but only if sizeof(long) == sizeof(int). On LP64 targets, where sizeof(long) == 2 * sizeof(int), 'long' and 'unsigned long' get encoded as 'q' and 'Q', respectively, instead.

Personally, I tend to think that this is broken, and that long should always be 'l', regardless of its size. However, I can also see an ABI argument (esp. in the context
of distributed objects) that would lead to the opposite conclusion.

What do you all think?
