[SciPy-user] GCC 3.3 requirement

Apple shipped a crippled version of GCC  3.3 with the new intel  
Macs.  (It seems like it is there -- there is a package, and you can  
gcc_select it -- but it does not work properly.)

Many on this list have discouraged using 4.0 for building scipy.  I  
have also found that 3.3 works on the *PPC* Mac, where 4.0 does not.   
However, it seems inevitable that mac users will need to compile with  
4.0 as more users get new Intel based machines.  I am sure that  
eventually someone will provide an unofficial gcc 3.3 package (like  
Guarav Khanna who maintains hpc.sf.net), but I don't think this is a  
good long-term solution.

What are the issues involved?  Why do we need gcc 3.3?  Is there some  
sort of timescale for moving the code base up to GCC 4.0 (or 4.x)
