Nic,
Unfortunately I am not well versed in either ant or autoconf configury.
I personally build the different versions by changing the JAVA_HOME
environment variable to point to the jdk I wish to use for building.
Ant then picks it up and does the 'right' thing. I personally haven't
tried building with gcj yet and I don't know if ant has support for gcj.
In general I would say that the driver has moved away from autoconf/make
and towards ant as the build mechanism. The role make now plays is
essentially just the wrapper around ant that ties into the overall
postgres build mechanism.
thanks,
--Barry
