Changes for SCO OpenServer and UnixWare 7

Migrated from rt.perl.org#1520 (status was 'resolved')

From root@devsys0.zenez.com

I have found the following patches are necessary to build perl on
UnixWare 7.x.x and OpenServer 5.0.x with both gcc and cc for the
platform in question. I have added the changes to get threads for
UnixWare 7.1.0.

Threads pass all test with the UDK cc, but with gcc-2.95.1 I get an
error but when I do the following with gcc-2.95.1...

shell> cd t
shell> ./perl harness lib/thread.t

lib/thread..........Confused test output​: test 11 answered after test 12
ok
All tests successful.
Files=1, Tests=14, 1 wallclock secs ( 0.23 cusr + 0.06 csys = 0.29 CPU)

I'll have to let you people who have access to svr4/svr5/sco boxes
to sort out these things. I'm rather good at hacking Configure/hints
"blind" but there are limits.

Unfortunately due a terminally damaged root file system I don't have
access to a Unixware 7 box at the moment...

I suspect it's more just a question of removing the UW 7 stuff from the
svr4 hints if we're going to use a new hints file for svr5. Of course if
the svr4 hints file has UW7 things that aren't in the svr5 hints then
they might need migrating.

Sorry for this new patch so soon Hops @​ sco pointed out that gccversion
was not yet set and recommended I add some info. I have attached these
changes.

[changes to detect gcc-2.95 and set -fno-strict-aliasing]

Thanks, but that's actually not necessary. In 5.005_62 and on, Configure
should automatically test for -fno-strict-aliasing. (No, I wouldn't
expect you to know that.)

Unfortunately due a terminally damaged root file system I don't have
access to a Unixware 7 box at the moment...

I suspect it's more just a question of removing the UW 7 stuff from the
svr4 hints if we're going to use a new hints file for svr5. Of course if
the svr4 hints file has UW7 things that aren't in the svr5 hints then
they might need migrating.

I started with the old svr4 hints file and modified it to work and find
everything. I have not done a diff because the changes were so many. It
should be just a remove the UW 7 stuff from svr4. So here is my
recommended patch to the svr4.sh file.

Thanks,
