Public bug reported:
Since the change to multiarch, building upstream gcc is broken on Debian
and Ubuntu 11.10. There are a load of reports at bugs.debian.org and a
proposed patch from Matthias Klose over at gcc-patches. However, the
former are not sorted out and the latter is not applied (yet).
How to reproduce: check out gcc from svn, try to build according to
documentation.
Result:
[...]
In file included from /usr/include/stdio.h:28:0,
from /home/daniel/svn/gcc-4.6/libgcc/../gcc/tsystem.h:87,

On my system, the file is here:
/usr/include/i386-linux-gnu/bits/predefs.h
Reports at Debian (I got lost trying to sort out which one is THE report):

Multiarch patch from Debain Maintainer (maybe someone could push this?):
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01674.html
Thinking I switched from Gentoo to Ubuntu hoping to avoid this constant
struggle uphill ... ha!
