I have just committed  a change to IcedTea that will simplify this 
process.  Though this procedure was done on a Gentoo system, it can be 
easily adapted to just about any Linux distro by changing the paths 
supplied to configure appropriately.

I have also got some input from the Gentoo Java team about using the GCJ 
overlay.  I have included it below as an alternative for anyone who 
wants to use that approach, is running Gentoo, and is comfortable using 
portage overlays.

OR if you are running Gentoo.

Use the Gentoo GCJ overlay, see instructions:
http://overlays.gentoo.org/proj/java/wiki/GCJ_as_a_JDK

Now that javac.in has been patched, it is no longer necessary to use the 
patch I sent, or modify the source tree in any way.  Simply:
> 3. Configure and build IcedTea
>   
> ./configure --with-ecj=/usr/bin/ecj-3.2
> --with-ecj-jar=/usr/share/eclipse-ecj-3.2/lib/ecj.jar
> --with-libgcj-jar=<gcc installation dir>/share/java/libgcj-4.1.3.jar
> --with-xalan2-jar=/usr/share/xalan/lib/xalan.jar
> --with-xalan2-serializer-jar=/usr/share/xalan-serializer/lib/serializer.jar
> --with-xerces2-jar=/usr/share/xerces-2/lib/xercesImpl.jar
> make
And there you have it.
