Don't feel bad about pressuring me.  You are not the only one with  
this problem.  Any model containing a protocol will break.

I did have a go at a Leopard build but the X windows config stuff  
broke.  Apple did some non-standard stuff when they upgraded the X11  
in Leopard.  I have reason to think this will be fixed in the imminent  
version 10.5.3 upgrade.  So I decided to wait rather than add yet  
another patch for a temporary issue.

I did not know that wrapper ever got turned off.

Sorry to be dense, but does the FSF compiler not label the sections at  
all?  Why should the Apple gcc 4.0.1 or 4.2 not work?

I will try to do a Leopard build, but I am off to Nepal for three  
weeks leaving on the 18th. So time is a bit short right now.
