Never mind, I figured it out.

Ant's build.xml (src/interfaces/jdbc/build.xml) decides whether
to build the 'enterprise' version of postgresql.jar by
checking whether the class javax.sql.DataSource is present.

The solution is to install the J2EE SDK, then make sure
j2ee.jar is in the classpath when ant builds the JDBC driver.

Example, my build script for all of PostgreSQL is now:

#!/bin/sh

CLASSPATH=/usr/local/java/j2sdkee1.2.1/lib/j2ee.jar
export CLASSPATH

make distclean
CC=gcc CXX=g++ CFLAGS=-O2 CXXFLAGS=-O2 \
./configure \
	--with-java \
	--enable-odbc \
	--enable-syslog
make -j 2
make check
