Fix partition detection in GNUMach

[Marco Gerards]

Hi,

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?:

http://lists.debian.org/debian-hurd/2001/debian-hurd-200105/threads.html#00300

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?

Thanks,
Marco
