With yesterday's updates to oea_machdep.c and to gcc4 I can now confirm
   that my macppc seems to build cleanly using gcc4.

cool.
   
   If I can get the serial console to work I might continue with my
   DECStation 5000/133 (in which case you'd probably hear my feedbacks
   about once a month :-) -- unless I cheat and cross-build).

mips isn't fully working yet....
