pfg 8c84995be2 Bring a couple of fixes for gcc optimizations.
The GCC4.3 branch contains some optimization fixes
that were not considered regressions and therefore
were never backported. We are bringing a couple of
them that are under GPLv2 since they were made
before the license switch upstream.

While here, add the GCC revision numbers in the
log.
