You can see the fix for python has been merged 5 days ago...

The problem is not the 4 byte alignment but changing the ABI.

You will create the exact same problem you want to fix: we can guess 
some softwares are built on linux/m68k with 2byte alignment in mind. So 
once the ABI is changed, you'll have to track them to fix them.

Adrian, I respect all the work you do for debian ports and particularly 
on m68k, but I want to point out that this ABI change can generate more 
problems than it solves.
