As I said: Don't use 2.96, except the world goes under otherwise. ;)

Ah, maybe crosstool is of interest for you. It allows you to build
different combinations of gcc, binutils and libc very easily. Just
google for it.

In this case removing -Werror should be fine. A gdb run of the
segmentation fault would be very interesting. I don't have an 8.2
machine here anymore, unfortunately.

gcc has never been without such side effects, and using stuff like
-Werror might give safety on a couple of systems, but also introduces
compilation problems on others. Is your gcc 3.3 a prerelease? (ie. as
shipped with SUSE a couple of times) those prereleases often handle code
better than the final releases, but they might have warnings enabled 
that never occur again in any later version.

Does the segfault you saw happen with the 2.96 binary as well? What did
you do to get around it?

Indeed. But please make sure to leave the mailing list off the senders
list in german mailings. ;-)
