It would be worth comparing with the current head. For example, the
"cond-optab" branch was merged a few weeks ago.

+  <dt>cond-optab</dt>
+  <dd>This branch is to clean up and simplify the implementation of
+  conditional operations (branches, stores, moves, etc.) in expand
+  and in the machine descriptions.

 In any case, the 4.3 series is not accepting novelties any more, only
regression fixes, 4.4 likewise, and 4.5 is the current development
series.

And yes, the gcc mailing list is the place to mention it,
alternatively file bugs in the gcc bug tracker or (best of all) post
patches to the gcc-patches mailing list that fix the faulty
optimizations. :)
