 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.
 
 Regards, Daniel
