Here are additional patches for the UnixWare 7 port.

Summary of changes:

In pqcomm.h, use the SUN_LEN macro if it is defined to calculate
the size of the sockaddr_un structure.

In unixware.h, drop the use of the UNIXWARE macro.  Everything can
be handled with the USE_UNIVEL_CC and DISABLE_COMPLEX_MACRO macros.

In s_lock.h, remove the reference to the UNIXWARE macro (see above).

In the unixware template, add the YFLAGS:-d line.

In various makefile templates, add (or cleanup) unixware and univel
port specific information.
