Fix partition detection in GNUMach

User-agent: Gnus/5.09 (Gnus v5.9.0) Emacs/21.3


This patch fixes the partition detection in GNUMach 1.x.  Now an error
is displayed when there is an extended partition on the harddrive.
See bug #6378 on savannah for details.

Roland, do you remember this thread?:


With autoconf 2.57 it is not possible anymore to make a working
configure.  Can you please update aclocal.m4 and configure.in or tell
me what needs to be done?

        * linux/dev/glue/block.c (init_partition): Don't check for BSD
        partitions if the DOS partition is too small.
