If anybody could regtest it, this is a regression from 3.3, likely to
be present in all 4.x branches.
I have tested it and ran the test suite and it does not seem to
introduce problems in gcc or g++. I am using the gcc-4.3-20061104
snapshot and the results from
http://gcc.gnu.org/ml/gcc-testresults/2006-11/msg00151.html.
