Enable thread safety on all platforms.  This will either be followed up
by a more extensive patch, or reverted, depending on the build farm
results.

There is no reference to THREAD_SUPPORT outside configure, and it is
never set, so remove it.

append_history(), if libreadline is new enough to have those functions
(they seem to be present at least since 4.2; but libedit may not have them).
This gives significantly saner behavior when two or more sessions overlap in
their use of the history file; although having two sessions exit at just the
same time is still perilous to your history.  The behavior of \s remains
unchanged, ie, overwrite whatever was there.
Per bug #5052 from Marek Wójtowicz.

with the not-so-deprecated DNSServiceRegister.  This patch shouldn't change
any user-visible behavior, it just gets rid of a deprecation warning in
--with-bonjour builds.  The new code will fail on OS X releases before 10.3,
but it seems unlikely that anyone will want to run Postgres 8.5 on 10.2.

Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit).  install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.

install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.

Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d.  For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).

This switches the man page building process to use the DocBook XSL stylesheet
toolchain.  The previous targets for Docbook2X are removed. configure has been
updated to look for the new tools.  The Documentation appendix contains the
new build instructions.  There are also a few isolated tweaks in the
documentation to improve places that came out strangely in the man pages.

and extend configure to test for it properly instead of hard-wiring
an assumption that everybody but Windows has the rand48 functions.
(We do cheat to the extent of assuming that probing for erand48 will do
for the entire rand48 family.)

erand48() is unused as of this commit, but a followon patch will cause
GEQO to depend on it.

This upgrades the configure infrastructure to the latest Autoconf version.
Some notable news are:
 - The workaround for the broken fseeko() test is gone.
 - Checking for unknown options is now provided by Autoconf itself.
 - Fixes for Mac OS X

the system's getopt_long().  The previous coding was the result of a sloppy
discussion that failed to draw this distinction.  The result was that PG
programs don't handle options as users of that platform expect.  Per
gripe from Chuck McDevitt.

Although this is a pre-existing bug, I'm not backpatching since I think we
could do with a bit of beta testing before concluding this is really OK.

CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report
from Mihai Criveti.

way pg_config.h is handled.  This avoids reruns of config.status on every
build, if configure has been rerun.

Also, if linked against other versions than the default MSVCRT library
(for example the MSVC build which links against MSVCRT80), also update
the cache in the default MSVCRT at the same time.

This should fix the issues with setting LC_MESSAGES on the MSVC build.

by me.

we can get some buildfarm feedback about whether that function is still
problematic.  (Note that the planned async-preread patch will not really
prove anything one way or the other in buildfarm testing, since it will
be inactive with default GUC settings.)

subdomains.

Since this means we no longer need fnmatch, remove the imported implementation
from port, along with the autoconf check for it.
