I think the pages under gcc.gnu.org/projects/ are all hopelessly
out-of-date and more recent (but still usually out-of-date) info
is found on the wiki.

So I'm not sure these kind of changes make sense.

Eventually we should remove those pages?  Or do we want
to keep them for historical purposes (and edit them to reflect
that purpose)?
