GCC-4 compiler bug

    Yah, it sounds like we need to get GCC updated.  Would someone like to
    take on that task?  We have about a month and a half to both do and
    test a compiler upgrade.

    I was rather surprised that the compiler barfed on that code.  That code
    was, in fact, explicitly testing for an overflow.  Regardless of what
    C99 says, it would be ultra stupid for any compiler to stray outside of
    the type's width.
