gcc4,amd64 - mk.conf?

[Dorian Büttner]

Marco's instructions, pointed to from the undeadly article, mentions to 
set COMPILER_VERSION=gcc4 in mk.conf, as opposed to current.html which 
does not list this step.

Does it make any difference having it in mk.conf or not? Propably this 
would have been explixitely mentioned in the 2010/05/09 change, if I'm 
not totally wrong.

Thanks,
Dorian
