[Monetdb-developers] Fix for enable-jdbc enable-xrpcwrapper arguments of MonetDB-java

Hi, The configure script for MonetDB-java uses the macro AC_ARG_ENABLE for its commandline arguments, but uses $withval instead of $enableval within that macro. The attached patch should fix the issue. It applies to Feb2009-SP1 bug fix release of the MonetDB suite. Thanks.
