I think Chris' suggestion is good that we first put a gcc-3.2 on one or
two spuds and spend a few weeks with them both to learn and debug.
I was not able to use some of the standard C++ features with gcc-2.96.
Given that my major work is C++ codes developement, I would really like to
learn how gcc-3.2 works.
