just some upgrade. As stated on my previous mail, I got gcc 4.5.5 to
ICE on fs/dcache.c.

Beside that I'm getting many of the following build error :

make[2]: *** [drivers/tty] Error 2
In file included from /src/linux/linux/include/linux/selection.h:11:0,
                 from /src/linux/linux/drivers/video/console/vgacon.c:45:
/src/linux/linux/include/linux/vt_buffer.h:18:21: fatal error:
asm/vga.h: No such file or directory

with the defconfig.

Moreover, I gave gcc 4.7.0 another try. The previous error got fixed,
but I'm getting 3 different ICE during the full build with today gcc's
source. Two of them related to the one I got on gcc 4.5.5. All have
been reported upstream.

ps: I do not really have a need of an h8300 kernel, all this is rather
to probe the state of the arch :) If there is to be more discussion
about this, maybe we should move on a dedicated thread.
