Hi all,
the attached patch started out as an ICE-on-invalid regression fix,
but after the ICE had been fixed recently by other means, it was
degraded to a mere error-recovery improvement. It removes some rather
'hackish' code that was added by Paul quite a long time ago.
Regtests cleanly on x86_64-unknown-linux-gnu. Ok for trunk?
Cheers,
Janus
