Thing is, the direction of all this work is toward not having xm-*.h
files at all.  I'm testing a patch right now that kills another 40 of
them, leaving us with

alpha/xm-vms.h      i386/xm-osf1elf.h     rs6000/xm-beos.h
arm/xm-arm.h        i386/xm-sco.h         rs6000/xm-darwin.h
convex/xm-convex.h  i386/xm-sco5.h        rs6000/xm-mach.h
i370/xm-mvs.h       i386/xm-vsta.h        rs6000/xm-rs6000.h
i370/xm-oe.h        m68hc11/xm-m68hc11.h  sparc/xm-linux.h
i386/xm-beos.h      m68k/xm-next.h        vax/xm-vax.h
i386/xm-cygwin.h    m68k/xm-plexus.h      vax/xm-vms.h
i386/xm-djgpp.h     m88k/xm-m88k.h        xm-interix.h
i386/xm-isc.h       mips/xm-iris5.h       xm-linux.h
i386/xm-mingw32.h   ns32k/xm-pc532-min.h
i386/xm-next.h      romp/xm-romp.h

and I could squash even more, but the patch is getting unwieldy.  All
of these do rather esoteric things which are unlikely to be of concern
to a sane, modern OS like OpenBSD.

There are only seven of these left with the patch I'm testing.  Alpha
is not one of them.

arm/xm-arm.h
convex/xm-convex.h
m68hc11/xm-m68hc11.h
m88k/xm-m88k.h
romp/xm-romp.h
rs6000/xm-rs6000.h
vax/xm-vax.h

xm-m68hc11.h shouldn't exist at all - it is a cross-compiler target
only.  xm-arm.h, xm-convex.h, and xm-vax.h only set the floating-point
format, which is not OS-specific (and will go away as soon as I have a
sane autoconf test for that).

xm-m88k.h, xm-romp.h, and xm-rs6000.h do indeed do OS- or compiler-
specific things.  xm-m88k.h and xm-romp.h only do them inside OS- and
compiler-specific #ifdefs; still wrong, but unlikely to cause
problems.

That leaves xm-rs6000.h, which is quite AIX specific, and
unconditionally so.  Unfortunately this is the one OpenBSD supports.
I should just rename the file rs6000/xm-aix.h.

I suggest you hold off until this series of patches settles down, then
reexamine what you have.  You may find you need to do a lot less work
in your host configuration.
