-O6 -mamdk6

If you encounter problems (very seldom) use a lesser optimization level.
Maybe you should also use -fno-exceptions for C-programs to get smaller
binaries since you won't need execptions in C in most cases. This option
will not improve speed.

I don't know if pgcc supports the Pentium II yet. Try -mpentiumpro and
look if it's faster...
