gmake compile fails using JDBC source.

Hi all,
I'm new to using postgress and download version 7.4.6 from your site
and started reading the documentation. Installed in /usr/local which is the
default. I installed ant because I am developing in java and want to use the
JDBC interface and added it to my CLASSPATH at /usr/local. Ran the
configure file as such:

./configure --with-pgport 9009 --with-java

Which seemed to work fine, the port number is an internal network thing I have
to use. Then I ran gmake which seemed to be working for awhile until it got
into compiling the java files
in /usr/local/postgresql-7.4.6/src/interfaces/jdbc/org/postgresql/jdbc3 in
which I get the following compile error:

/usr/bin/ant -buildfile ./build.xml all
Buildfile: ./build.xml

It looks to me like the driver code that determines and compiles the
correct driver for my JVM based on my JDK doesn't compile as intended. As a
result, I never get the postgresql.jar and installed in the share/java
directory. Did I leave a step out or is this a bug. Any help with this would
be appreciated.
Thanks in advance, Michael.
