    True, Wagner... But compiler manufacturers DO answer the phone
    when it rings, and sometimes the person on the other end of the
    line says something like, "Hi, [Walter/Clyde], this is
    [Andy/Scott/whomever].  Y'know, you can save an instruction in
    your 16-bit subtractions by...."

    When that happens, the next version of the C compiler generally
    includes those optimizations.  In other words, specific compiler
    optimizations are often developed by a whole TEAM of people,
    most of whom don't even work for the compiler manufacturers.
