State-Changed-Why:
    This is the same as the frequently reported non-bug.
    
    Glibc defines printf as a macro if optimization is on.
    At the top of your file, put #undef printf to solve this.
    GCC 3.2 allows you to put directives in macro arguments,
    so this Gblic issue disappears, but the changes will
    not be backported to 3.1 .
    
    Why was the message reported by the compiler unclear to
    you?  I'm worried as I don't think I can make it any clearer.
