P. S.   Other optimizations that don't cause crtdll.dll to crash are
"-O5 -mpentium", "-O -mpentium", "-O5", etc.  Using "O5 -mpentium"
causes a noticeable speed increase in lynx.exe operation.

I should mention that this is a "Morgan" (disfigured Athlon XP) AMD
processor at 1000 Mhz., but I think the problem should also occur with
the previous "spitfire" series.  People using Linux on an AMD system
might want to change the optimization settings on their Makefile files
to determine whether the problem is repeatable under Linux.

Also, this motherboard is an "all in one" motherboard, with the PCI
video card interrupt tested at "on" and "off" (leave it "off" for best
onbard video performance).  And, the L2 cache is disabled on this
motherboard, because leaving it enabled doesn't improve benchmark
performance or gcc compile speed, and disabling L2 lowers the operating
CPU temperature by several degrees fahrenheit.
