from my point of view, linux and bsd are the same OS; plan 9 is the hard 
one. I need to modify plan 9 for all of these. At the same time, if I 
understood how to hack the compiler in the manner you describe, it would 
probably not take long at all.

likewise. It's a big effort to track Xen 3.0 nowadays, with the current
rate of change, and the effort is highly magnified by the fact that Plan 9
does not use gcc.
