I have a core 2 duo (EM64T) (e6400) with WinXP pro SP2 32bits =>

PROCESSOR_IDENTIFIER=x86 Family 6 Model 15 Stepping 6, GenuineIntel

With the same kind of processor (xeon 5100) on Vista pro 64bits =>

PROCESSOR_IDENTIFIER=EM64T Family 6 Model 15 Stepping 6, GenuineIntel

Will try it as soon as I can (not before Monday since the problematic system
is at work)

Also thanks for documenting the 64bits compilation because there wasn't a
lot of information before (I had a hard time finding the good bjam option)
