Why do you need to know the size of 'long'?  Its size is not guaranteed
by the language spec.  If you're writing portable code, you should not
assume any more than the language guarantees.

If you need an integer of a specific size, use types like int32_t or
int64_t.  These are part of C99 and C++0x.  If they don't exist on some
platform you need to support, they are easy to typedef.

That said, if you already have a tonne of code.....
