Any idea/ressource to point me to?
I tried to build the 0.16 sources, and ran into the kind of trouble 
(unrecognizable	insn, this time in generictree.cpp file)

Should I consider submitting a bug to gcc/Debian gcc? Many people seem 
to build AMD64 flawlessly... Did anyone succed on a Debian pure64 system?
