gcc 3.4 vs 4.0

[adler at stephenadler.com (Stephen Adler)]

Hi,

I'm looking to do a rather major software upgrade. Currently the project 
I'm working on is running 2.4 kernel flavored enterprise linux and I'm 
looking to switch to the 2.6 kernel flavored enterprise linux. This 
basically means moving from gcc 3.2 to gcc 3.4. I also have the option 
of using gcc 4.0 instead. Does anyone have any advice of the advantages 
of gcc 4 over gcc 3.4?

Thanks. Steve.
