Thanks, I've found 
http://sources.redhat.com/ml/gsl-discuss/2001/msg00727.html
which says that I should switch to gcc-3.0. That's what I did, and I go a
bit further. But not that much ;)

How did you turn the optimization of ? by editing all Makefiles, or there is
a magic option to the ./configure ?



Thanks, Mt.
