No idea. I think that current options (/G6 /Ox /Gr, combine all sources into
one/two files) will be the best, but cannot be sure. You can experiment - try
different settings. I'd recommend:
(1) try optimization for different CPU family - /G5 or even /G4,
(2) Try to control inlining - add /Ob1 after /Ox,
(3) Maybe it'll be good idea to turn off part of the inline assembler, as I am
not sure how fast BSF/BSR are on K6. Unfortunately, it's not easy to turn it off
for only FindFirst/FindLast, some source modifications are necessary.

In any case, try to install VC6 SP3 before doing experiments.
