I think it would sufficient to:

1. Compile only .jar and .class with gcj (not .java).
2. Pass all unit tests on a single platform.

This would provide an existence proof that Lucene can run under GCJ, and 
doesn't require solving GCJ's porting issues.

The patches to JavaCC-generated code should probably really become 
JavaCC patches.  Have you looked into that?  Most of the rest look like 
reasonable changes to Lucene, except perhaps the "native matches", which 
looks a bit fishy for Lucene's trunk.
