    Geoff, I think you're being overly harsh -- the bug report
    includes everything one needs to reproduce the problem. I
    see the very same reported problem on my linux box. It
    should be simple for you as well to reproduce this.

    x.cc:679:2: anonymous variadic macros were introduced in C99
    
    Note also the bogus line number 679, which certainly doesn't
    exist in this file.
