Indeed.

Looking through the various config files, I see the following that
set HAVE_SYSIPC but that don't set HAVE_SOCKETS:

        m/7300.h m/ibmrs6000.h m/ns16000.h s/usg5-3.h s/xenix.h

m/7300.h: last changed in 95.
m/ibmrs600.h: has USUAL-OPSYS="aix3-1" and s/aix-3-1.h defines HAVE_SOCKETS.
m/ns16000.h: last changed in 94.
s/usg5-3.h: looks like the last real change was in 93.
s/xenix.h: seems to only have had cosmetic changes since rev 1.1 in 91.

When I say "last changed in 95" I don't count changes that seem to
have been global (moving stuff from [sm]/*.h to autoconf and things
like that).

I think it's safe to ignore those ancient systems,
any disagreement ?
