Whilst I'm looking at OSLib, and you didn't reply to my earlier request,
presumably what we need here is a new call, with a signature:

 extern os_error *xbuffer_modify_flags2 
      (buffer_b b,
       bits eor_mask,
       bits and_mask,
       bits *old_value,
       bits *new_value	
       );

OK?

(cc'd in case you're still having problems with the list)
