    I was mistaken.  gcc 2.95 complains when main() is not noreturn, which
    caused me to declare main() as noreturn.  Later, I upgraded to gcc
    3.0, which complains when main() is noreturn.
    
    The warning described in the original bug still seems wrong to me, but
    it's much less bothersome.  I'll admit to being a perfectionist though ;)

    Yes.

    Fine by me.
