which directory pure64 or gcc-3.4?

["Kristian G. Kvilekval" <kris@cs.ucsb.edu>]

I have some homegrown packages that are having trouble
with gcc-3.3 on pure64.  They seem to compile well
with gcc-3.4, but I have lot of library dependences
and would like to move everything over to gcc-3.4

What is the status of the gcc-3.4 repository?  
Is it in a usable state and how complete is it compared
to pure64?

Is it possible to just point apt at that repository to
upgrade.  

Thanks for any guidance.
