This is OK for mainline. Thanks for the speedy fix. If there are no
problems on mainline after a few days, and it bootstraps and regression
tests against the gcc-3_4-branch, OK there too. It also appears to be
a 3.3 regression, so the same for the gcc-3_3-branch in order to close
the PR in bugzilla.
Many thanks,
Roger
