The snapshot on the main download page seems to be some really ancient
thing.  Don't use it.  (We really need to raise a bug about that!)

If you want a proper snapshot, follow the "Browse CVS Directory" link,
then the "comedi/" directory link, then use the "Download tarball" link
at the bottom, or just use this:

<http://www.comedi.org/cgi-bin/viewcvs.cgi/comedi.tar.gz?view=tar>

You really need to use ./autogen.sh as the configure script from 0.7.70
will be out of date.  In fact it would be better to unpack the CVS
snapshot into a clean directory.

Instead, you could try: ./configure --enable-kbuild

Just start afresh!
