        * src/num_put.cpp [_RWSTD_OS_SUNOS]: Removed the #inclusion of
        <sunmath.h> mistakenly introduced in rev 646597 as the functions
        declared in the header are defined in libsunmath that we don't
        link with and don't want to start.
        [_RWSTD_OS_SUNOS] (__rw_signbit): Reimplemented using simple
        integer arithmetic. Needed to complete the patch for STDCXX-51  
        initially committed in rev 646396.
