I am also fine with it.
I think that if anybody has strong objections, now is the time to make
them. Otherwise I think we should go with this plan.
To me, the basic summary of the idea is that there is no clear reason
to ever change the GCC major version number. There were real
objections to changing it when we went from 3 to 4. There will be
real objections for any future change from 4 to 5. At the same time,
we face the fact that going from 4.9 to 4.10 will break some people's
existing scripts, as is also true of any other decision we can make.
Given that there is no clear reason to ever change the major version
number, making that change will not convey any useful information to
our users. So let's just drop the major version number. Once we've
made that decision, then the next release (in 2015) naturally becomes
5.0, the release after that (in 2016) becomes 6.0, etc.
