The real problem isn't with compilers that issue warnings,
it is with compilers (such as BSD's) that issue the warning and
then go ahead and interpret "x=-1" as "x -= 1".
Issue the warning, fine, but please interpret it the "correct" way,
not the way that has been wrong for a decade.  If they had done that
all along, the old code would have been fixed by now instead of
being left as it was since it still compiles ok if you ignore the
warings.
