* 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.
