It can be a pain to upgrade gcc, and in fact for me this is much
harder than updating the kernel for example.  If I upgrade gcc it
effects all of my development work, not just the work I do with glibc.

Yes I could just have a compiler in a separate PATH just for glibc
work, but that isn't convenient either.

I suspect a lot of people trying to maintain older architectures and
keep glibc working on them are in this situation too.

I understand the features/longterm-maintainence arguments, but like
-Werror and friends, there is a cost for contributors with less time
and resources than the most active contributors.

Just my $0.02
