Note that despite my public comments about it beign a bad idea to ship
extremely untested compilers in a major release, I actually think that
it would be wonderful to have people who are ready to face the
consequences to try the new 2.96. 

It's not been all that widely tested, but if you kno a bit about what
you're doing (or want to learn), gcc-2.96 _does_ potentially create
better code, and if nobody is willing to test it, any potential bugs (be
they in the kernel sources and triggered by a smarter compiler, or in
the compiler itself) won't be found. 

So please do try it out, but please mention the fact if you end up
having to report a bug (it won't make your bug-report be ignored, don't
ever worry about something like that. But i would be good to have an
older compiler handy to correlate the bug with the compiler for sure).

In fact, I'd love to hear about experiences even with the CVS snapshots.
I just don't like them showing up in distributions ;)
