My mailer munged the intro text in my last post. Here is the text

in a more readable form.  -- I am submitting the following patches
to the June 6, 1998 snapshot of PostgreSQL.  These patches implement
a port of PostgreSQL to SCO UnixWare 7, and updates the Univel port
(UnixWare 2.x).  The patched files, and the reason
 for the patch are:

File            Reason for the patch ---------------
---------------------------------------------------------------
src/backend/port/dynloader/unixware.c src/backend/port/dynloader/unixware.h
src/include/port/unixware.h src/makefiles/Makefile.unixware
src/template/unixware
		Created for the UNIXWARE port.

src/include/port/univel.h
		Modifed this file to work with the changes made to
		s_lock.[ch].

src/backend/storage/buffer/s_lock.c src/include/storage/s_lock.h
		Moved the UNIXWARE (and Univel) tas() function from
		s_lock.c to s_lock.h.  The UnixWare compiler asm
		construct is treated as a macro and needs to be in
		the s_lock.h file.  I also reworked the tas()
		function to correct some errors in the code.

src/include/version.h.in
		The use of the ## operator with quoted strings in
		the VERSION macro caused problems with the UnixWare
		C compiler.  I removed the ## operators since they
		were not needed in this case.  The macro expands
		into a sequence of quoted strings that will be
		concatenated by any ANSI C compiler.

src/config.guess
		This script was modified to recognize SCO UnixWare
		7.

src/configure src/configure.in
		The configure script was modified to recognize SCO
		UnixWare 7.
