So, I built the kernel on gcc-4.7.0 from pkgsrc on DragonFly, and lo and
behold the kernel seems to work (at least it boots) and then page faults later
while running the hello application, this might be something entirely
different now, and I might have to investigate what could have gone wrong.
(DragonFly build of the svn version fails because of -nostdinc and stddef.h
includes sys/types.h, so I just added /usr/include again which might have
caused a mess)

Thanks for the help so far. As soon as ArchLinux updates their gcc I will try
again and try to find out whether there's something funny going on with
ArchLinux' multilib compiler.

Cheers,
 Markus
