Hi Folks,

I got an answer from comp.unix.sco.programmer.

Yes, and in UnixWare 2, and in the upcoming Open UNIX 8.0.0 as well.

Yes, you can do this.  (On SCO OpenServer this will not work at
all, but on all UnixWare and Open UNIX it will.)  You will lose
some performance doing this, since the pages that contain non-PIC
code will be replicated for each process using them instead of
being shared, but it will work correctly.

Yes, you should be able to successfully do this test.

Based on that, I'm not comfortable with my patch.
As I mentioned, UnixWare 7.x.x is identified as an

   i586-sco-sysv5uw7.x.x

and my patch is caught by the sysv) option, then the sco) option.
But I don't know how to adjust this for UnixWare 2.1.3, though.

Thanks,
Matthew
