State-Changed-Why:
    Perhaps I'm missing something, but I'm not certain what you
    think the bug is here.  You cannot declare names already
    used in the library and expect the compiler to distinguish
    between them, once you pull all the library names into the
    same namespace as your own variable.
    
    The fix you list would therefore seem to be the only
    correct way to write the code, if you must use names that
    could collide with the standard library (count, cerr, cos,
    and so forth).
