The test case that Autoconf uses to discover whether a function has
been declared doesn't work reliably with clang, because clang reports
a warning not an error if the name is a known built-in function.
On some platforms, this results in a lot of compile-time warnings about
strlcpy and related functions not having been declared.
There is a fix for this (by Noah Misch) in the upstream Autoconf sources,
but since they've not made a release in years and show no indication of
doing so anytime soon, let's just absorb their fix directly. We can
revert this when and if we update to a newer Autoconf release.
Back-patch to all supported branches.

LLVM will be used for *optional* Just-in-time compilation
support. This commit just adds the configure infrastructure that
detects LLVM.
No documentation has been added for the --with-llvm flag, that'll be
added after the actual supporting code has been added.

The TAP tests mostly don't work without IPC::Run, and the reason for
the failure is not immediately obvious from the error messages you get.
So teach configure to reject --enable-tap-tests unless IPC::Run exists.
Mostly this just involves adding ax_prog_perl_modules.m4 from the GNU
autoconf archives.
This was discussed last year, but we held off on the theory that we might
be switching to CMake soon. That's evidently not happening for v10,
so let's absorb this now.

Add a column collprovider to pg_collation that determines which library
provides the collation data. The existing choices are default and libc,
and this adds an icu choice, which uses the ICU4C library.
The pg_locale_t type is changed to a union that contains the
provider-specific locale handles. Users of locale information are
changed to look into that struct for the appropriate handle to use.
Also add a collversion column that records the version of the collation
when it is created, and check at run time whether it is still the same.
This detects potentially incompatible library upgrades that can corrupt
indexes and other structures. This is currently only supported by
ICU-provided collations.
initdb initializes the default collation set as before from the `locale
-a` output but also adds all available ICU locales with a "-x-icu"
appended.
Currently, ICU-provided collations can only be explicitly named
collations. The global database locales are still always libc-provided.
ICU support is enabled by configure --with-icu.

Our version was different from the upstream version in that we tried to use
all possible pthread-related flags that the compiler accepts, rather than
just the first one that works. That change was made in commit
e48322a6d6, to work-around a bug affecting GCC
versions 3.2 and below (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=8888),
although we didn't realize that it was a GCC bug at the time. We hardly care
about that old GCC versions anymore, so we no longer need that workaround.
This fixes the macro for compilers that print warnings with the chosen
flags. That's pretty annoying on its own right, but it also inconspicuously
disabled thread-safety, because we refused to use any pthread-related flags
if the compiler produced warnings. Max Filippov reported that problem when
linking with uClibc and OpenSSL. The warnings-check was added because the
workaround for the GCC bug caused warnings otherwise, so it's no longer
needed either. We can just use the upstream version as is.
If you really want to compile with GCC version 3.2 or older, you can still
work-around it manually by setting PTHREAD_CFLAGS="-pthread -lpthread"
manually on the configure command line.
Backpatch to 9.5. I don't want to unnecessarily rock the boat on stable
branches, but 9.5 seems like fair game.
Allow additional thread flags to be added via port templates.
Change thread flag names to PTHREAD_CFLAGS and PTHREAD_LIBS to match new
configure script.
bits in JDBC & the first set of tools into contrib.
This is the third, and deals with enabling JDBC to be compiled with the main
source.
What it does is add a new option to configure: --with-java
This option tells configure to look for ant (our build tool of choice) and
if found, it then compiles both the JDBC driver and the new tools as part
of the normal make.
Also, when the postgresql install is done, all the .jar files are also
installed into the ${PGLIB}/java directory (thought best to keep then separate)
Now I had some conflicts when this applied so could someone please double check
that everything is ok?

add --without-tk option to disable Tk. We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X. Also make sure that libpq is up to date for
libpgtcl. Remove executable bits from pgaccess.sh, but add it to pgaccess.
incarnations (I hope). When an acceptable flex version is not found, print
instructive error messages from both configure and the makefiles, so that
users can continue building anyway.
argument, change the order of tests for the third argument to be safe
against missing prototypes, and make it fail hard if none of the
combinations succeed.
we'll get there one day.
Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.
Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.
Interfaced a lot of the custom tests to the config.cache, in the process
made them separate macros and grouped them out into files. Made naming
adjustments.
Removed a couple of useless/unused configure tests.
Disabled C++ by default. C++ is no more special than Perl, Python, and Tcl.
And it breaks equally often. :(
that now functions as a wrapper around the MakeMaker stuff. It might
even behave sensically when we have separate build dirs. Same for plperl,
which of course still doesn't work very well. Made sure that plperl
respects the choice of --libdir.
Added --with-python to automatically build and install the Python interface.
Works similarly to the Perl5 stuff.
Moved the burden of the distclean targets lower down into the source tree.
Eventually, each make file should have its own.
Added automatic remaking of makefiles and configure. Currently only for the
top-level because of a bug(?) in Autoconf. Use GNU `missing' to work around
missing autoconf and aclocal. Start factoring out macros into their own
config/*.m4 files to increase readability and organization.
