C/C++ Memory Leak Detection on Windows

Memory leak tracer by Jochen Kalmbach (http://blog.kalmbachnet.de/). You just need to include the files in your project and call his initialization, finalization routines. The output log gives you call stack, size of the request and believe it or not...source file and line number of the allocation request. Works with both malloc and new.
