/*
 * Purpose of this file :
 *
 * Defines all STLport settings.
 * This file is actually a wrapper : it includes compiler-specific
 * settings from <config/stlcomp.h> (<config/stlconf.h>, if you ran "configure),
 * and user-defined settings from <stl_user_config.h>.
 * See <config/stl_mycomp.h> and <stl_user_config.h> for the description
 * of those macros
 * 
 */
// Other macros defined by this file:

// * bool, true, and false, if __STL_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 (__STLPORT_STD, __STL_BEGIN_NAMESPACE, etc.)
// * exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
// * __stl_assert, either as a test or as a null macro, depending on
//   whether or not __STL_ASSERTIONS is defined.
