The claim was made as an argument against using a beta version of v3.0 in
RedHat v7.x distros. You're correct that no 3.x release was available when
the statement was made. Check out: http://www.bero.org/gcc296.html
So now that we have the v3.00 and 3.01 releases (with 3.02 imminent), how
do they stack up against RedHat's compiler?
