The mingw people don't appear to care about compatibility with non-GNU
versions of getopt, so force use of our own copy of getopt on Windows.
Also, ensure that we make use of optreset when using our own copy.
Per report from Andrew Dunstan. Back-patch to all versions supported
on Windows.
wait until it is set. Latches can be used to reliably wait until a signal
arrives, which is hard otherwise because signals don't interrupt select()
on some platforms, and even when they do, there's race conditions.
On Unix, latches use the so called self-pipe trick under the covers to
implement the sleep until the latch is set, without race conditions. On
Windows, Windows events are used.
Use the new latch abstraction to sleep in walsender, so that as soon as
a transaction finishes, walsender is woken up to immediately send the WAL
to the standby. This reduces the latency between master and standby, which
is good.
Preliminary work by Fujii Masao. The latch implementation is by me, with
helpful comments from many people.
linking both executables and shared libraries, and we add on LDFLAGS_EX when
linking executables or LDFLAGS_SL when linking shared libraries. This
provides a significantly cleaner way of dealing with link-time switches than
the former behavior. Also, make sure that the various platform-specific
%.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that
before. (I did not add these variables for the platforms that invoke $(LD)
directly, however. It's not clear if we can do that safely, since for the
most part we assume these variables use CC command-line syntax.)
Per gripe from Aaron Swenson and subsequent investigation.
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings. It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

posix_fadvise and other file-related functions can depend on _LARGEFILE_SOURCE
and/or _FILE_OFFSET_BITS. Per report from Robert Treat.
Back-patch to 8.4. This has been wrong all along, but we weren't really using
posix_fadvise in anger before, and AC_FUNC_FSEEKO seems to mask the issue well
enough for that function.
provide a working 64-bit integer datatype. As recently noted, we've been
broken on such platforms since early in the 8.4 development cycle. Since
it took nearly two years for anyone to even notice, it seems that the
rationale for continuing to support such platforms has reached the point
of non-existence. Rather than thrashing around to try to make it work
again, we'll just admit up front that this no longer works.
Back-patch to 8.4 since that branch is also broken.
We should go around to remove INT64_IS_BUSTED support, but just in HEAD,
so that seems like material for a separate commit.
This is more in keeping with modern practice, and is a first step towards
porting to Win64 (which has sizeof(pointer) > sizeof(long)).

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.
on AIX with a non-gcc compiler. The previous coding would do this only if
CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report
from Mihai Criveti.
