 * See <config/stl_mycomp.h> and <config/user_config.h> for the description

 * namespace-related macros (_STLP_STD, _STLP_BEGIN_NAMESPACE, etc.)
 * exception-related macros (_STLP_TRY, _STLP_UNWIND, etc.)
 * _STLP_ASSERT, either as a test or as a null macro, depending on
   whether or not _STLP_ASSERTIONS is defined.
