gcc 2.95.4 vs gcc 3.3 ?

gcc 2.95.4 vs gcc 3.3 ?

  I'm trying to compile the 2.4.21-ac3 kernel for some work machines.
One of the users is insisting on gcc 3.3 to compile.  Reading the
web page on www.kernel.org this is recomended against.

  Perchance is this old news, is the 3.3 compiled kernel going to kill
something or anything that should be related to users or any bosses?

gcc 3.3 is relatively new and _much_ less tested than 2.95. A new gcc 
might either contain bugs or it might unleash bugs in the kernel that 
weren't visible before (e.g. via better optimizations).

Usually gcc 3.3 works fine (and my PC at home runs a 2.4.21 compiled
with 3.3) but if you want stability in production envvironments 2.95 (or
the unofficial 2.96 >= 2.96-74) is the recommended compiler.

It should work, some drivers still don't build with it however
