** BYTE MAGAZINE'S NATIVE MODE BENCHMARKS **
**           FOR CPU/FPU                  **
**             ver 2.0                    **
**       Rick Grehan, BYTE Magazine       **
********************************************
** NOTE: These benchmarks do NOT check for the presence
** of an FPU.  You have to find that out manually.
**
** REVISION HISTORY FOR BENCHMARKS
**  9/94 -- First beta. --RG
**  12/94 -- Bug discovered in some of the integer routines
**    (IDEA, Huffman,...).  Routines were not accurately counting
**    the number of loops.  Fixed. --RG (Thanks to Steve A.)
**  12/94 -- Added routines to calculate and display index
**    values. Indexes based on DELL XPS 90 (90 MHz Pentium).
**  1/95 -- Added Mac time manager routines for more accurate
**    timing on Macintosh (said to be good to 20 usecs) -- RG
**  1/95 -- Re-did all the #defines so they made more
**    sense.  See NMGLOBAL.H -- RG
**  3/95 -- Fixed memory leak in LU decomposition.  Did not
**    invalidate previous results, just made it easier to run.--RG
**  3/95 -- Added TOOLHELP.DLL timing routine to Windows timer. --RG
