Great, I would suggest committing enabling LRA after the imminent stable release
for the next major GCC version. It would be nice to revert the deprecation if possible.
But in practice if of course does not really if we build the next stable release with
--enable-obsolete it just would look better.

Yes, as far as I am concerned we are only caring about Linux support. I guess
that could mean extra work for me carefully only deleting hpux code then?

I’ll send out the copyright assignment mail later today.
How can we get this Steeting Committee pointing going?
