To have only gcc-3.2 on the spuds is not a good idea until we also have
it on all blast machines including dblast. It was mentioned that gcc-3.2
was more compliant but I was not aware of any decision. It is not a personal
issue but as you know Root is definitely not compliant and we rely heavily
on it. I don't see the rush, given also the points below:

_ Ernie bisson must be made aware so that once we are happy with gcc-3.2
  we can schedule an installation on all other machine. Note the word
  schedule ! He very much prefers that way, but so do we!! think of all
  the various root versions here and there not so long ago.

- Not everybody everywhere uses gcc-3.2. At least we should provide a way
  to have a way to have two different compilations (src trees) and not
  break the experiment.

- gcc-3.2 won't speed up the code or fix bugs in the existing code. We are
  supposed to use the existing code for an aymmetry measurament next week...

- It will be wonderful to have gcc-3.2 for the v3 release, which already
  is not "backward" compatible.

- I have no problems if you install gcc-3.2 as an alt compiler on the
  spuds. I have problems if we can't compile with gcc-2.96 anymore on the
  spuds.
