| 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. | |
