------- Comment #1 from rsandifo at gcc dot gnu dot org  2008-03-09 16:51 -------
This is one of the issues that I originally tried to fix for 4.3:

    http://gcc.gnu.org/ml/gcc-patches/2007-10/msg01661.html

but that was too invasive for stage 3.  I resubmitted it after 4.4 opened:

    http://gcc.gnu.org/ml/gcc-patches/2008-02/msg01227.html

and pinged it yesterday:

    http://gcc.gnu.org/ml/gcc-patches/2008-03/msg00537.html

I'll add the PR number to the change log.
