patch: fix up compiling of libpq on the 8.3 stable branch

Hi,

I tried to compile the head of REL8_3_STABLE (on x86 linux) and ran into:

In `/var/tmp/.build-1914/postgresql-8.3.0_080303/src/interfaces/libpq':
make[3]: *** No rule to make target `libpq.rc.in', needed by `libpq.rc'. Stop.

A quick lookaround revealed that the culprit is the following commit which
removed src/interfaces/libpq/libpq.rc.in but failed to update the Makefile
(and .cvsignore, for that matter).

commit 69db64c737012a8d2d6fbcce3ace7136cb2bc85f
Author: branch-fixup <branch-fixup>
Date: Wed Feb 13 03:40:38 2008 +0000

Removing files not present on branch REL8_3_STABLE:
configure
configure.in
doc/bug.template
src/include/pg_config.h.win32
src/interfaces/libpq/libpq.rc.in
src/port/win32ver.rc

Patch with a possible solution attached.

Best regards,

Complement commit 69db64c "removing files not present on branch
REL8_3_STABLE" to get libpq to compile again.
