I know we are already OT here, but...

Code-generation correctness wise, which GCC version is the most stable 
one? What about ld (the linker) and the rest of binutils, are they also 
affected by the changes in 4.x? I know they try to keep the 
compiler|linker separating walls thick most of the time, but I can think 
of scenarios where they must coop.

As I expect it to be 3.3.x, downgrading from 4.x, what features will I 
lose (I know speed for one)?

I'm interested to hear as many opinions as possible.
