- cleaned out unused variables
	- added missing prototype headers

One outstanding -Werror failure:

/home/staff/scrappy/postgres/2.0/cvs/postgres95/src/backend/access/gist/giststra
t.c:117: warning: missing braces around initializer for `GISTEvaluationData.expr
ession'

indextuple.c:159: warning: `bp' might be used uninitialized in this function

this directory passes -Wall -Werror under FreeBSD

of it

Once access/* is cleaned out, will redo using -Wall on compile to
make sure that all prototyping is correct

Mainly...fix up the includes I removed, as well as prototypes

Pointed out by D'Arcy

FreeBSD/NetBSD both ship with gcc 2.7.x

that allows one to compile libpq++

this should be set on a port-by-port basis

files

access/common...how many more directories to go? :)

absolutely required
