No, it fails.

If it's only important to know if it's i386 or ix86 and we don't need
to know x, then that would be fine for the SVR5 boxes. (UnixWare 7, OpenUNIX 8)
The 4.2MP machines (UnixWare 2.x) could be running an i386 but I doubt
anyone would. (UnixWare 1.1 was slow enough on a 386)
It's probably safe to hard code i586 in the 4.2MP section.
Dump the OpenUNIX section at line 96, (it's bogus, Release is 5)
...
System = OpenUNIX
Node = ou8
Release = 5
KernelID = 01/06/09
Machine = Pentium II
BusType = ISA
Serial = 3IH026825
Users = 5
OEM# = 0
Origin# = 1
NumCPU = 1
...
Have the 5 section look something like
----------
5)
if [ "`echo x$VERSION | sed -e 's/\..*//'`" = "x7" ]; then
echo "i586-sco-unixware7"; exit 0
elif [ "`echo x$VERSION | sed -e 's/\..*//'`" = "x8" ]; then
echo "i586-unknown-OpenUNIX${VERSION}"; exit 0
fi
;;
----------
An argument in favor of knowing which processor it really has would
be if at some future date we wanted to automaticly use
say, crypto/des/asm/des686.pl instead of
crypto/des/asm/des-586.pl on i686.
