Release numbering

[kenner at vlsi1 dot ultra dot nyu dot edu (Richard Kenner)]

I'd like to re-raise the issue of whether the next release should be
3.5 or 4.0.

There seems to be a fundamental disagreement here as to numberings.

Despite Mark just saying that "The tree-ssa changes are a huge perturbation",
he doesn't feel it's large enough to justify a move to 4.0 due to not having
enough user-visible changes.  A large number of other people on this list
agree with that view.

Others, including me, Robert Dewar and a different large number of people
on the list, feel that the internal changes are enough to justify the
version number change because we want to give users notice that this is
a major change.  The change in Fortran is also a large user-visible change.

We've been through this discussion on the list a number of times and have
not come to any conclusion.  I doubt we can, so I'm not suggesting we
start discussion on this size list.

However, I believe that this is a large enough issue that it should be
raised before the entire SC and see what conclusions they come to.
So I'd like to request that the SC take up this issue.
