        Merge from 'apple/trunk' branch on FSF servers.  Removed small
        change in build_conditional_expr that had been added when fixing
        PR objc/27377 and which did the same check in a less complete way.

------- Comment #12 from ayers at gcc dot gnu dot org  2009-04-08 12:03 -------
Since the branch still isn't frozen, I've finally committed this simple fix on
the release branch also.
Regression fixed... PR closed.

------- Comment #9 from jsm28 at gcc dot gnu dot org  2009-03-31 19:35 -------
Closing 4.2 branch.  Removing 4.5 from summary since it appears a patch
has been committed to trunk.
