------- Comment #3 from aldyh at gcc dot gnu dot org  2009-06-13 21:28 -------
Wshadow-3.c and pr36902.c are definitely mine.  My original request for
approval indicated that these were problems with fold being location agnostic,
and that I would be addressing the issues post merge.  The func-ptr-conv-1.c
regression I will investigate, as it did not show up on my tests.

Mee too!  I mean, seen for cris-elf too!
BTW, isn't it odd that for recent regressions, the committer's testing never
seem to have shown the regressions seen by "every other target" after commit? 
1/2 ;)
(Definitely _not_ just you, Aldy.)

To add something useful, I should have mentioned that they were ok for 148440,
regressed for 148444 for cris-elf, so that leaves only commit's from Aldy and
Steven B., IIUC.

All regressions are caused by revision 148442, including
gcc.dg/func-ptr-conv-1.c. You may need to enable checking
to see it.
