    Compiling with GCC 4.8 yields several instances of

    Converting the macro to an inline function eliminates this problem.
    
    However, doing only that causes problems with the GCC 3.x series.  The
    inline function cannot be named "memset", as otherwise we wind up with
    recursion via __builtin_memset.  Solve this by adjusting the symbols
    such that __memset is the inline, and ___memset is the real function.
