Just a note that reverting this patch:
http://gcc.gnu.org/ml/gcc-patches/2003-02/msg01334.html
fixes this regression. Reverting that patch
Jan said that his patch did not change the results of the test, so presumably
something else changed somewhere.
Reverting that patch removes most of the warnings from c90-const-expr-3.c and
c99-const-expr-3.c, although we still get warnings for +0.0, 0.0+0.0, and
(double)0.0.

This bug is not fixed, but the 4.0 regression has been fixed. 4.0 now fails in
the same way as earlier gcc versions.

Adding "gcc.dg/c9[09]-const-expr-3.c" to the summary so I don't get confused between this bug and
PR 456.
