I totally disagree : things are implemented the way they are today 
because old exception code was so broken and had so many feature in 
ifdefs (no more used and not even compiling e.g gcc272, ...) that 
modifying it for all platform was something I refused to do.

Now, I think motorolla_shared supports by itself  more platform than you 
listed for old exception processing. And BTW, the same exception model 
is used on Ix86 and the code is shared. The problem was that the powerpc 
code and the old BSP were to different to unify anything.

And BTW do anything you want because I will no more use RTEMS on PPC. So 
make any modification you want provided you support them.
