Indeed. I noticed this problem when compiling code declaring a variable.
I cut it down to report it to GNATS, but it seems I cut it down too much
(as the problem with the old parser occured before it saw the variable).
I consider it fixed now, the example I gave in the original error report
is clearly illegal. Thanks to the whole GCC team.
