Missing declarations/jdbc error

Hello
We are currently trying to set up postgresql 7.4.3 on RedHat Enterprise
linux WS 2.4... for use on a software platform called DSpace, as such we
have also installed Java 1.4.2, Apache-Ant and Tomcat 5.0.19 which are
required for use with Dspace. We have been unable to get past the gmake
command in the installation of Pgsql.

We had been adviced of a possible pre-existing JDBC driver conflict, we have
since deleted any *jdbc.jar file as well as any postgresql.jar file and have
still encountered the following errors after the gmake command.

What can be the cause of the 'Wmissing-declarations'. and what (if anything)
has to be done before running ./config or gmake.

This is the line at which the error occured in the build.xml file: <javac
classpath="{$srcdir}" srcdir="${srcdir}" destdir="${builddir}"
debug="${debug}">

This is the error generated by the gmake command :

pgc.c:1436: warning: label `find_rule' defined but not used
