AFAICT, gcc4's default behavior is to warn about

    int    foo;

    somefunc(&foo);

which unfortunately is a very common usage that I'm not real thrilled
about having to fix every occurrence of.  I've been meaning to look into
whether they provided a pragma or something to mark function parameters
as output-only, so that this message could be suppressed where
appropriate without adding a lot of useless initializations.

In the meantime, I don't see the point of patching just one place.
