Java 7 on OS X Snow Leopard

 From googling I guess this is Java 7 on OS X Snow Leopard again. It  
seemed this has been discussed and resolved on this list before.
I recently got curious about trying some Java 7 features so I tried  
to do a openjdk build as detailed here...
Building OpenJDK for Mac OS X 10.6 (Snow Leopard) | java rants
http://www.javarants.com/2009/11/01/building-openjdk-1-7-0-for-mac-os- 
x-10-6-snow-leopard/

With the 32 bit Soylatte.

My first problem as I remember was compile errors due to something  
ambiguous related to pointer types and a movptr macro.
Google seemed to indicate that this was an Apple difference in a type  
being 64 bit no longer being castable with 32 bit pointer types.

More googling turned up a openjdk changeset that seemed to apply.
http://hg.openjdk.java.net/jdk6/jdk6/hotspot/rev/db4caa99ef11

This is my first attempt at mercurial so I wasn't quite sure what to  
do with this but eventually went for the same process of doing an 'hg  
fclone' on the changeset url as indicated in the original  
documentation. This seemed to get me past this error.

However, I started running into another error. I saved a copy of part  
of that...

So far google hasn't turned up anything similar. So I really have no  
idea how to proceed on this one, suggestions appreciated.
