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

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.)
