Devel::PPPort instead.  Thanks to Gilles Darold for doing the legwork.

DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.

DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because

a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.

b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.

(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

to one another. Sort out builddir vs srcdir variable namings. Remove some
now obsoleted make variables.

standard targets and behaviour. Replaced Makefile.in's with
Makefile's and declared the respective variables in Makefile.global.

maintainer-clean target now available at top level, although it does
not work in the backend tree yet.

Cleanup pass over Makefile.shlib, renamed some targets and variables.
The shared library symlink tests are now done by make, not the shell.

ecpg: Remove one warning in sloppy flex output.

PL/Perl and Perl interface: the MakeMaker documentation is confusing,
the realclean target *does* "delete derived files", but it also
uninstalls them. Don't use that.

The submake targets in the various bin directories that update libpq
should `make all', not `make libpq.a'. That is a) unportable, and
b) doesn't build the shared library.

all the standard semantics. Also get rid of Makefile.in's on the
way and instead declare all variables in Makefile.global.
