13// the goal of this file is to define wxCrtSetDbgFlag() macro which may be
14// used like this:
15//      wxCrtSetDbgFlag(_CRTDBG_LEAK_CHECK_DF);
16// to turn on memory leak checks for programs compiled with Microsoft Visual
17// C++ (5.0+). The macro will expand to nothing under other compilers.
