Technically, PHP doesn't guarantee this -- just that the return value will
be less than 0. It could be -42.

You are completely right Toby. Which makes me wonder why there's such a
loose definition of the retval, and what is actually stored in it inside
the func.

Sig fixed anyways.

I suspect this goes back to the C strcmp, which has the same definition. Some C compilers return exactly +1, -1 or 0. Others return the numeric difference between the two. The latter is slightly faster in machine code.
