----------
Mark,

Don't give up yet!  Here are some more results to consider:

VAX 8600 4.3 BSD UNIX (gcc -O)              4.2 sec
VAX 8600 4.3 BSD UNIX ( cc -O)              4.5 sec 
Amiga 2000 (68030/33MHz, ICache ON,
	    DCache ON, Burst OFF)           9.6 sec
Amiga 2000 (68030/25MHz, ICache ON,
	    DCache ON, Burst OFF)          12.3 sec
Amiga 2000 (68030/25MHz, ICache OFF,
	    DCache OFF, Burst OFF)         14.3 sec
Grid LapTop  386/12.5MHz (Turbo C V2.0)   173.6 sec
Zenith Z-248 286/ 8.0MHz (Turbo C V2.0)   282.4 sec

The results may not represent (ahem) 'typical' usage, but they
are real results after all (as long as some didn't extraordinarily tweak
the code).
