Compilation with dmalloc heap checker

DMALLOC:

• checks access beyond boundaries of dynamically allocated memory blocks.
• checks heap leaks (unallocated blocks on program exit)
• logs every allocation-deallocation to the log file

To compile with DMALLOC:

1. install dmalloc into directory named dmalloc at the level your LK8000 source directory is placed
   • a) download dmalloc-win32.zip and unpack it into directory, or
   • b) download dmalloc source codes and compile them yourself (don't forget set appropriate INTERNAL_MEMORY_SPACE)
2. clean build (delete Bin/PC)
3. call make TARGET=PC DMALLOC=y

DMALLOC is controlled by environment variables. See lk.bat in dmalloc-win32.zip for example.
