 * Defines all STLport settings.
 * This file is actually a wrapper : it includes compiler-specific
 * settings from <config/stlcomp.h>
 * and user-defined settings from <config/user_config.h>.
 * See <config/stl_mycomp.h> and <config/user_config.h> for the description
 * of those macros

/* Other macros defined by this file:

 * bool, true, and false, if _STLP_NO_BOOL is defined.
 * typename, as a null macro if it's not already a keyword.
 * explicit, as a null macro if it's not already a keyword.
 * 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.
