This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).

Here's a fix for a tiny memory leak in PQsetdb/PQfinish.

(Analysis of a running program indicates there are several others, but
this is the only obvious one I saw in the code).

This fixes a problem in ResultSet.getDate() when the column is NULL
(reported by Vincent Partington <Vincent.Partington@nmg.nl>)

And fixes a problem with Field's (ResultSet.getObject() was proving to be
slow as it repetedly send queries for oid -> name mapping - fixed by
creating a cache. (reported by Mario Ellebrecht <ellebrec@nads.de>)

PGDOCS in Makefile.custom will supercede defaults here, I think...

	gram.c updated
	scan.c updated
	ecpg/Makefile added LDFLAGS
	configure requires sfio for those systems with it installed...

This will force the aix compiler to insert trapping code to
check for division by zero for the 4.1 port.

documented in ./configure --help

Here is a pair of patches that (I hope) finish the configuration
issues with tcl/tk and make the recognition of the two packages
completely parallel in organization.  This should make future changes
easier to maintain.

Hope to see this in 6.2.2.

Marc, I overlooked this file it should be included in the source.  Oops
Also the binary file is only 1.2 meg not 2.5 meg. Oops again.

This one is based on an older PostODBC driver, rewritten and maintained by
InsightDist(?)
