// the goal of this file is to define wxCrtSetDbgFlag() macro which may be
// used like this:
//      wxCrtSetDbgFlag(_CRTDBG_LEAK_CHECK_DF);
// to turn on memory leak checks for programs compiled with Microsoft Visual
// C++ (5.0+). The macro will not be defined under other compilers or if it
// can't be used with MSVC for whatever reason.

// builds
