State-Changed-Why:
    Problem was fixed on mainline at some point.  Fixed on
    3.0.X branch before 3.0.4 release with:
    
    2002-01-28  Jens Rehsack <rehsack@web.de>
    
    	libstdc++/3561
    	* include/bits/ostream.tcc (__pad_char): Support -Wshadow -Werror.
    
    Here was my final analysis of the PR:
    
    It appears that being marked as code within a system header does not
    affect template instantiation that is actually triggered outside the
    header.  If this issue only arose when one was compiling libstdc++-v3
    (as I first thought), then we could just say, "don't compile
    libstdc++-v3 with both flags" but this issue impacts building user
    code outside the library with strict warning flags.
    
    The problem had nothing to do with prefix configuration.
