GCC 4.xx FC4 rc3 x86_64

[James Black]

I found out that many packages can't compile with gcc v4. Since Fedora 4 
will be released soon it might be a good idea for compatibility reasons 
to also include the gcc v3. It also would be nice if Fedora includes a 
scrift to switch temporally from gcc v4 to gcc v3 something like 
gcc_choose or something... I know for compatibility reasons you have 
include the gcc32 but it's a 32 bit not a 64 bit compiler.
The issue affect multimedia software like Xvid, Mplayer etc.
I would apreciate your answer
