 // 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 expand to nothing under other compilers.
+// C++ (5.0+). The macro will not be defined under other compilers or if it
+// can't be used with MSVC for whatever reason.
