Well, the alpha's been using a patched 2.7.2.3---but the patches are
integrateable into the mainline sources, although this hasn't yet been
done. I think there's a big bug report in the system with the
changes.

Unfortunately, egcs has more development weight than gcc for *all of
our other* architectures, sparc, alpha, i386 and powerpc. Also, I
have gotten things to compile with egcs that simply do not compile
with gcc-2.7.2.3 on alpha. Of course, emacs20 didn't compile with
egcs, so there's obviously some tradeoffs.
I guess my feelings are this:
We don't have a libg++ for anything but 2.7.2.3, and since we have at
least one Debian system-specific tool (menu) that uses it, it would
look bad to move away from that compiler.
Once there's a libg++, and once egcs-1.0.2, which is supposed to be
c++ compatible with 2.8.X, then architectures should be easily able to
choose.
Mike.
