1.  The UnixWare tas macro was reformatted (by indent or it like?) which caused
    it to break.  The asm macro construct is very particular about the %mem
    construct -- it has to start in column 1.

2.  When compiling libpq++, g++ was used even if configure found the C++ com-
    piler to be CC.

3.  When compiling libpq++, '-Wno-error' was added to CXXFLAGS, even if the
    compiler wasn't g++.

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.

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.

NS32K machine I contributed.  In any case, I now have postgresql-6.3
running again on NetBSD/pc532, a NS32532 machine.  The following
changes are needed relative to the src directory.  (It looks like
support was partially removed when the files were moved from the
src/backend/storage/.... tree to the src/include tree.)

If you need me to get a current development version of postgresql
for this change let me know.  Also, let me know if this code needs
updating due to another code movement that deleted the old NS32K
support.

Thank you.

GCC, the inner "#if defined(__GNUC__)" can just be omitted in that
architecture's block.

The existing arrangement with an outer "#if defined(__GNUC__)"
doesn't have any obvious benefit, and it encourages missed cases
like this one.


BTW, I'd suggest making the definition of clear_lock for HPUX be

static const slock_t clear_lock = {{-1, -1, -1, -1}};

The extra braces are needed to suppress warnings from gcc, and
declaring it const just seems like good practice.

			regards, tom lane

but as I don't have access to a sparc for testing I just did what
I could. I am guessing here, but please apply the following to your
pgsql and let me know what happens. Also, cd to src/storage/buffer
and do 'make s_lock_test' as well.

This incorporates all the precedeing patches and emailed suggestions
and the results of the performance testing I posted last week. I
would like to get this tested on as many platforms as possible so
I can verify it went in correctly (as opposed to the horrorshow
last time I sent in a patch).

Once this is confirmed, I will make a tarball of files that can be
dropped into a 6.3.2 source tree as a few people have asked for
this in 6.3.2 as well.

Attached patch will add a version() function to Postges, e.g.

template1=> select version();
version
------------------------------------------------------------
PostgreSQL 6.3.2 on i586-pc-linux-gnu, compiled by gcc 2.8.1
(1 row)

        Ok, I have finally gotten all of the defines for Dec/Alpha and
Linux/Alpha sorted out as Marc asked. There is no longer any need for
'-Dalpha' or '-Dlinuxalpha' in either the Dec/Alpha or the Linux/Alpha
template files (./src/template/{alpha,linuxalpha}). I have replaced every
instance of 'alpha' or '__alpha__' with '__alpha', as that appears to be
the common symbol between C compilers on both operating systems (RH4.2 &
DecUnix 4.0b) for alpha.

The following patches will allow postgreSQL 6.3 to compile and run on a
UNIXWARE 2.1.2 system with the native C compiler with the following library
change:

        The alloca function must be copied from the libucb.a archive and added
        to the libgen.a archive.

Also, the GNU flex program is needed to successfully build postgreSQL.

Only occurrs in
src/include/storage/s_lock.h:#if defined(__AIX)
src/include/utils/dt.h:#if defined(__AIX)
src/include/utils/nabstime.h:#if defined(__AIX)

Simply delete one underscore, only occurs once per file, so no patch.

Apart from this Makefile hack, all I've done is to make dynamically
loaded code modules fail properly (as was already done for __mips__,
although I think this is too loose: I believe NetBSD for the pmax can
do dynamic linking), and to add test-and-set lock handling.  As Bruce
suggested, this is done in a maximally efficient inlined way: I was
not aware that this code was so important, speed-wise.

Small patch for sparc solaris/tas()

Add lock to i386 asm.

The attached patches will allow postgreSQL to compile successfully on SCO
UNIXWARE 2.1.x.  The patches fix the following problems:

1.  Configure did not properly recognize the UNIXWARE system as needing the
    univel port.  It used the sys4 port.

2.  Configure did not properly process the CC flag in the template file.

3.  There was no working test and set locking implementation for the native
    UNIXWARE compiler.

4.  The test and set locking used for Intel X86 that was selected by defining
    NEED_I386_TAS_ASM could fail in a multi-processor environment.

5.  The makefiles for libpq and libpgtcl did not make a shared library for
    the univel port.
