OK. I did it the right way and installed gcc-2.95.2. Now I can compile and
run (!!!) Glide3.
I've checked all (I hope) combinations of the optimization flags and found a
very nice one.
Without AMD 3DNow! optimizations
CNODEBUG = -O6 -ffast-math -fomit-frame-pointer \
-malign-double -mpreferred-stack-boundary=5 \
-funroll-all-loops -fexpensive-optimizations -DBIG_OPT
Very, very fast!!! Best I've ever seen:-)
But with the AMD 3DNow! optimizations enabled it crash (as expected).
Holger I hope this is helpful:

Daryll and Holger what are you thinking about 3DNow! prefetch(w)
optimizations for texture management (loading)? I saw that the 3dfx code use
the 3DNow! instructions for this.
