I'll probably commit a patch that enables 4-way universal builds for  
Python 2.6 on Leopard later this week.  That patch is more involved  
than just patching a header file, I've also enabled building most of  
the Carbon bindings in 64-bit mode (by disabling everything that isn't  
supported in 64-bit mode).

The patch should be complete by now, I just have to do some more  
testing before I commit.
