From 4e9408f19825cf62714518d8932f18563b44cd7b Mon Sep 17 00:00:00 2001

Subject: Add PSEUDO_NOERROR similar to that used by NetBSD. Some ports were
 setting errno in PSEUDO and some were not.  Now errno is set for all in
 PSEUDO and PSEUDO_NOERROR is provided for the non-errno case (only used by
 _exit).

Needs testing on vax and m88k.
XXX - hppa and powerpc still lack a real PSEUDO_NOERROR implementation.
Currently PSEUDO_NOERROR and PSEUDO are the same (so builds don't
break on those platforms).
