I would like to help, but what do you mean by ``before and after''? I can
imagine running c++ compiler with profiling info producing some profile
output, but what's this before and after, I really don't know...

Pray will certainly help, but I'll try to get some numbers for you.
Anyway, I hope someone already described how to compile gcc with profiling
information so I'll be able to find it in the archive...

Thanks,

Karel
