/* File used to define macros:
 * _STLP_USE_DYNAMIC_LIB: To signal use STLport as a dll or build of the
 *                        STLport dlls.
 * _STLP_USE_STATIC_LIB: To signal use of STLport as a static lib or build of
 *                       the STLport static libs.
 * _STLP_USING_CROSS_NATIVE_RUNTIME_LIB: Signal that we are using a native runtime
 *                                       in a version different from the STLport one.
 * If _STLP_USE_DYNAMIC_LIB or _STLP_USE_STATIC_LIB is alreday defined it means that
 * user forces use of a specific version. In this case _STLP_USING_CROSS_NATIVE_RUNTIME_LIB
 * will surely be defined otherwise there is no need to force macro defines.
 *
 * Before including this file the compiler must define:
 * _STLP_DLL: If we are building a dll
 * _STLP_RUNTIME_DLL: If we are using native runtime as a dll
