gdb 6

[ibotty]

due to public (hello to Greece) interest, i have ported gdb 6 :)
with CCVER=gcc3 (i can hear jippee yells far away).

well, this is not tested (just started), but anyway.

i have put an pre-built image on [1]. i will not commit a port override, as
i do not like the port system, and will likely destroy something.
(but i may import gdb in base, if i am asked politely.)

i will pots a patch tommorrow, when i am awake.
