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. Discussed with: jkim MFC after: 1 week
