Peter Eisentraut 4446565d36 Use better comment marker in Autoconf input
The comment marker "#" is copied to the output, so it's only
appropriate for comments that make sense in the shell output.  For
comments about the Autoconf language, "dnl" should be used.

Peter Eisentraut 29b3ac7546 configure: More use of AC_ARG_VAR
AC_ARG_VAR is necessary if an environment variable influences a
configure result that is then used by other tests that are cached.
With AC_ARG_VAR, a change in the variable is detected on subsequent
configure runs and the user is then advised to remove the cache.

This adds AC_ARG_VAR calls for: MSGFMT, PERL, PYTHON, TCLSH, XML2_CONFIG

Tom Lane b21c569cea Further improve consistency of configure's program searching.
Peter Eisentraut noted that commit 40b9f1921 had broken a configure
behavior that some people might rely on: AC_CHECK_PROGS(FOO,...) will
allow the search to be overridden by specifying a value for FOO on
configure's command line or in its environment, but AC_PATH_PROGS(FOO,...)
accepts such an override only if it's an absolute path.  We had worked
around that behavior for some, but not all, of the pre-existing uses
of AC_PATH_PROGS by just skipping the macro altogether when FOO is
already set.  Let's standardize on that workaround for all uses of
AC_PATH_PROGS, new and pre-existing, by wrapping AC_PATH_PROGS in a
new macro PGAC_PATH_PROGS.  While at it, fix a deficiency of the old
workaround code by making sure we report the setting to configure's log.

Eventually I'd like to improve PGAC_PATH_PROGS so that it converts
non-absolute override inputs to absolute form, eg "PYTHON=python3"
becomes, say, PYTHON = /usr/bin/python3.  But that will take some
nontrivial coding so it doesn't seem like a thing to do in late beta.

Tom Lane 40b9f19217 Record full paths of programs sought by "configure".
Previously we had a mix of uses of AC_CHECK_PROG[S] and AC_PATH_PROG[S].
The only difference between those macros is that the latter emits the
full path to the program it finds, eg "/usr/bin/prove", whereas the
former emits just "prove".  Let's standardize on always emitting the
full path; this is better for documentation of the build, and it might
prevent some types of failures if later build steps are done with
a different PATH setting.

I did not touch the AC_CHECK_PROG[S] calls in ax_pthread.m4 and
ax_prog_perl_modules.m4.  There seems no need to make those diverge from
upstream, since we do not record the programs sought by the former, while
the latter's call to AC_CHECK_PROG(PERL,...) will never be reached.

Tom Lane 7d7b129277 Fix configure's incorrect version tests for flex and perl.
awk's equality-comparison operator is "==" not "=".  We got this right
in many places, but not in configure's checks for supported version
numbers of flex and perl.  It hadn't been noticed because unsupported
versions are so old as to be basically extinct in the wild, and because
the only consequence is whether or not a WARNING flies by during
configure.

Daniel Gustafsson noted the problem with respect to the test for flex,
I found the other by reviewing other awk calls.

Tom Lane 32f15d05c8 Accept flex > 2.5.x in configure.
Per buildfarm member anchovy, 2.6.0 exists in the wild now.
Hopefully it works with Postgres; if not, we'll have to do something
about that, but in any case claiming it's "too old" is pretty silly.

Heikki Linnakangas a2edb023d0 Replace obsolete autoconf macros with their modern replacements.
AC_TRY_COMPILE(...) -> AC_COMPILE_IFELSE([AC_LANG_PROGRAM(...)])
AC_TRY_LINK(...) -> AC_LINK_IFELSE([AC_LANG_PROGRAM(...)])
AC_TRY_RUN(...) -> AC_RUN_IFELSE([AC_LANG_PROGRAM(...)])
AC_LANG_SAVE/RESTORE -> AC_LANG_PUSH/POP
AC_DECL_SYS_SIGLIST -> AC_CHECK_DECLS(...) (per snippet in autoconf manual)

Also use AC_LANG_SOURCE instead of AC_LANG_PROGRAM, where the main()
function is not needed.

With these changes, autoconf -Wall doesn't complain anymore.

Peter Eisentraut 55fb759ab3 Silence Bison deprecation warnings
Bison >=3.0 issues warnings about

    %name-prefix="base_yy"

instead of the now preferred

    %name-prefix "base_yy"

but the latter doesn't work with Bison 2.3 or less.  So for now we
silence the deprecation warnings.

Peter Eisentraut 5dd41f3574 Remove maintainer-check target, fold into normal build
make maintainer-check was obscure and rarely called in practice, and
many breakages were missed.  Fold everything that make maintainer-check
used to do into the normal build.  Specifically:

- Call duplicate_oids when genbki.pl is called.

- Check for tabs in SGML files when the documentation is built.

- Run msgfmt with the -c option during the regular build.  Add an
  additional configure check to see whether we are using the GNU
  version.  (make maintainer-check probably used to fail with non-GNU
  msgfmt.)

Keep maintainer-check as around as phony target for the time being in
case anyone is calling it.  But it won't do anything anymore.

Peter Eisentraut b748d8f280 Fix install-strip on Mac OS X
There was a hack put into install-sh to call strip with the correct
options on Mac OS X.  But that never worked, because configure
disabled stripping on that platform altogether.  So remove that dead
code, and while we're at it, update install-sh to the latest upstream
source (from Automake).

Instead, set up the right strip options in programs.m4, so this now
actually works the way it was originally intended.

Tom Lane da4b900176 Advance the minimum required version of "flex" from 2.5.4 to 2.5.31, and

an easy reference if we later decide to make the minimum something different
(like 2.5.33).

Tom Lane aef2d0d86c Fix readline/libedit selection code to prefer readline over libedit
reliably (ie, regardless of which libraries they depend on).  Also
make sure that we don't select headers that obviously belong to the
wrong one of the two libraries.  This was discussed back around 4-Sep
but seems to have slipped through the cracks.  The header selection
could be checked more closely, perhaps, but let's see if this is good
enough.
