gfortran 4.4 regressions

[Tobias Burnus]

Hello,

I think we should try to cut down the number of gfortran regressions
before 4.4 will be frozen/released.

Current 4.4 status:
  98 serious regressions P1/P2/P3 (fulfils criterion < 100 PRs)
of which
  5 are P1 (goal: 0 P1; solution: Fixing or downgrading)
  4 are not yet triaged (= P3)

Richard's guess was that the trunk will not be frozen before 4.3.3 is
released (-> end of this week?) but presumably it will be frozen before
1 February.


To the gfortran regressions: There are 9 bugs; ignoring 4.3-only and
suspended bugs - and the P1 ABI (non)issue, we are left with the
following 5 PRs:

   (a one-line patch by Mikael exists, which may nor may not be enough)

  (If I understood correctly, Jerry might have a patch which should
still get in 4.4. I think fixing this can be deferred to 4.5.)
