That is true, but which vars (in configure/Makefile.global etc) define this?
Also what about the platforms that don't use the GNU FSS?

Anyhow, it's easy as it's defined on one line

Ah, you are getting confused. The java directory is beneath the one install
makes for postgresql already, not along side, so for example (based on my
laptop NT/Cygwin):

/usr/local/pgsql/lib where PGLIB is
/usr/local/pgsql/lib/java where the .jars are put.

The top one is used to refer to both src/interfaces/jdbc/build.xml and
contrib/retep/build.xml, that way running ant at the bottom builds the lot.

Originally I was going to get ANT to run from there directly, but found I
couldn't easily add it into the rest of the build sequence easily, hence why
there's the reference back to the base xml file from interfaces/jdbc.

Perhaps later we can remove that hack and get it working from the base one.

May be for 7.1.1, add a "test" target to the base build.xml file. If it runs,
then the test passes.

I'm trying to concentrate on many bug fixes (so far none needed - touch wood ;-
) ) getting the tutorials done and porting the tools over (the contrib stuff)
ready for 7.1.

The one thing I didn't put in there is getting the version numbers out of
Makefile.global. It's just a couple of -D parameters to add to
interfaces/jdbc/Makefile. build.xml and Driver.java.in already support them.
