I'm not volunteering, but want to raise the "the stack is misaligned"
issue... at least I haven't seen a commit ehich says the opposite (and I
paid attention to this issue since
<Pine.BSF.4.21.0005070611030.8973-100000@besplex.bde.org> (should be in
the archive of -current)).
If someone picks up the OpenBSD commit it should be easy to align the
stack at the same time.
