 *  The Memory Manager is a very thin layer on top of the native memory
 *  heap functions, allowing strong assertion checking and pointer
 *  validation in debug builds.
 *
 *  Author:
 *  Benjamin W. Slivka
 *
 *  History:
 *  10-Aug-1993 bens    Initial version
 *  11-Aug-1993 bens    Lift code from STOCK.EXE win app
 *  12-Aug-1993 bens    Improved comments
 *      18-Mar-1994 bens    strdup() now called _strdup(); renamed
 *      18-May-1994 bens    Allow turning off MemCheckHeap() in debug build
 *                              (it can really, really slow things down!)
 *
 *  Functions:
 *  MemAlloc  - Allocate memory block
 *  MemFree   - Free memory block
 *  MemStrDup - Duplicate string to new memory block
 *
 *  Functions available in ASSERT build:
 *      MemAssert       - Assert that pointer was allocated by MemAlloc
 *      MemCheckHeap    - Check entire memory heap
 *      MemListHeap     - List all heap entries (to stdout)
 *      MemGetSize      - Return allocated size of memory block
 *      MemSetCheckHeap - Control whether MemCheckHeap is done on every
 *                          every MemAlloc and MemFree!
