Here's what a libgcj source RPM could look like (using FC5)... http://people.redhat.com/green/libgcj-4.1.1-1.fc5.src.rpm This source RPM builds, so feel free to try it. You'll see that the SOURCES directory contains a script called libgcj-copy-source.sh. This script generates the libgcj source tarball from portions of the prepped gcc sources. Using a libgcj source RPM like this means we can easily add our own patches, rebuild and deploy on a schedule that is independent from the gcc update schedule. I'm going to have sporadic email access for the next 10 days or so. I just wanted to get this out for comment before I take off. Thanks, AG
