instead of relying on port's os.h to tell us.  (Needed for HPUX
where system major version is not enough info.)
configure unsets USE_TK if X libraries not found.
doc/Makefile uses gzcat or zcat as found by autoconf.

selected when they match a prefix of the  value.  The previous method,
which stripped all version data from  and then tried to match that
against .similar entries, was entirely useless when .similar contained
several entries for different version numbers of a single OS name.

slight mods required for freebsd (elf vs aout stuff)

oops, forgot one part of the patch...remove 'false' setting to ELF_SYS...

Minor FreeBSD fixes put in place

From: SHIOZAKI Takehiko <takehi-s@ascii.co.jp>

I tried snapshot(Oct30) and made some patches.
# I think that it is confused to manage both Makefile.shlib and
# makefiles/Makefile.*, don't you?

* configure
        Now FreeBSD 2.X is not supported..., so I added its entry.
        If ELF_SYSTEM is set, gmake treat it defined even though
        it is "false".  So nothing should be set to use "ifdef".
        BSD_SHLIB etc. may have same problems.

* Makefile.shlib
        As you said, FreeBSD entry is much like BSD's.
        I only added ELF_SYSTEM code.

* makefiles/Makefile.freebsd
        Ifdef/else/endif can not be indented with TABs.

Okay, this shoudl provide a fix for the freebsd problem...

Added a ELF_SYS variable and check to configure.in...

Starting with v3.0 of FreeBSD, we are now an elf system, and dont' have a
-Bforcearchive flag for ld...

Give FreeBSD its own special Makefile to get around the "bug"

This time, src/interfaces/perl5/Makefile.PL no longer needs to be autoconf'd.

 from stdin. Necessary at least for systems missing cpp but having gcc -E.
Include new configured file backend/catalog/genbki.sh.

From: Peter Gucwa <pg@softcomputer.com>

Here are patches needed to complie under AIX 4.2.
I changed configure.in, pqcomm.c, config.h.in, and fe-connect.c.
Also I had to install flex because lex did not want to translate pgc.l.

change configure so that if postgresql isn't being installed as root,
do not configure in the perl5 interface.

the perl5 interface needs to be installed under /usr/local/lib/perl5/*, which
is generally owned by root.  This allows a non-root build/install with the
only root requirement being the make/install of hte perl5 stuff...

Autoconf

 Before, "make install" did not run the lextest.
Fix up the ODBC make from this main configure.
Include configure test for "ln -s" in Makefile.global.in.
 Was always in configure, just not carried through to here for use.

Suppress installing man pages from here; do it from the doc/Makefile now.

to behave sanely.  configure was not treating it as BSD...
