:Hi Folks,
:I'm upgrading my work desktop to a Athlon64 3500 - Socket 939 - K8N Neo2
:I'm assuming it should 'just' work in 32 bit mode, but I'm also
:curious as to whether or not or how I can build 64 bit applications?
:I just tried a simple test with gcc34 -
:-- root at atrens: ~ (13:40) --
:# cc -O9 -march=athlon64 -o x x.c
:-- root at atrens: ~ (13:41) --
:# cc -O9 -march=athlon-xp -o x2 x.c

    We don't support 64 bit execution environments yet.  We won't for a
    while, a bigger chunk of the core infrastructure has to be dealt with
