New __mp_atexit() and __mp_setmark() functions, more fields to the information returned by __mp_info(), and better source-level information when __mp_check() is called. A new FREMRK error, a fix for a problem which prevented const being used when compiling with a C++ compiler, fixes for a problem when profiling memory reallocations and a typing error which would prevent compilation on Windows platforms, and fixes for std namespace problems for set_new_handler() on Windows platforms. HEAPDIFFSTART() and HEAPDIFFEND() were lowercased, and support was added in the heapdiff tool for marked memory allocations. Dbmalloc-compatible function implementations were added as an external package, and the trace file in the mtrace tool is automatically closed at exit.
