Yes, but your example compiles fine with the HP compiler version I have as
well.  Evidently only some cases of |= assignment to bitfields are
affected.

Can you bootstrap the trunk with your version of the HP compiler?
(Configure with CC=cc if you have gcc installed).

In any case, it's a simple, one-line patch to fix the problem, so I would
prefer to get it installed.  Users are sometimes conservative about
upgrading compiler versions.

In any case, this is now PR 12186, and the patch can be found at
