Actually I have to correct myself here.  After studying the layout code a 
bit I see that TCC implements mostly microsoft's bit-field layout.  We 
don't want to get rid of that capability, so GCCs layout (which is PCC 
layout for i386 and arm AAPCS, and funky layout for legacy arm) would have 
to be implemented in addition.


Ciao,
