Peter Eisentraut 9d182ef002 Update of install-sh, mkinstalldirs, and associated configury
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).

Timezone
========

This is a PostgreSQL adapted version of the timezone library from:

	ftp://elsie.nci.nih.gov/pub/tzcode*.tar.gz

The code is currently synced with release 2007k.  There are many cosmetic
(and not so cosmetic) differences from the original tzcode library, but
diffs in the upstream version should usually be propagated to our version.

The data files under data/ are an exact copy of the latest data set from:

	ftp://elsie.nci.nih.gov/pub/tzdata*.tar.gz

Since time zone rules change frequently in some parts of the world,
we should endeavor to update the data files before each PostgreSQL
release.

At each update, we should check if time zone offsets have changed.
Just search for the current or previous year and see what has changed.
Sometimes a country changes its time zone offsets, for example Georgia
in 2004.  Just grepping in the zic database files for 2004 is enough to
spot such a change.  Then the files under tznames/ should be updated.
