It looked like the default optimization settings were "-g -O2". Now that
I think about it, that might have been only in the CFLAGS but not in the
CXXFLAGS. Yep, there's the problem. So the default compiling results in
no optimization at all because at least on my system, it's the CXXFLAGS
that are being passed to g++. I placed my optimization flags in both
CFLAGS and CXXFLAGS (leaving the NOMULTICHAR part in the CXXFLAGS
intact). Of course, my optimization settings included targeting the
Athlon architecture. But even without those machine specific flags, the
other optimizations should help.
It would be nice to have a faster pre-compiled Linux binary available
for people to use. Alternatively, maybe some optimized versions like
Micha's p3 one could be provided in addition to the generic (slow :P)
binary.
