Thanks for your help. The compiler I used to build Pistachio is
gcc32/g++32, and here is part of the output of `make'

According to your suggestion, I disable the SMP support and it is OK now.
Thanks :-).

I build Pistachio just to do some experiments, and I think the SMP version
is more
general than UP version, so I prefer SMP support enabled even not needed.
