I think we shouldn't answer this question before we've sawn SGI's
standalone shell.  I remember some people on this list saying that they'd
like to have a standalone shell for their ARC machines.

If you use autoconf you can live without gmake much easier.  While beliving
that it's good not to rely on the GNU tools this is not really necessary.
After all they're available for free :-)

Hmm...  if you want to configure the Milo-package (possibly supporting
multiple host environments in the future) we'll need a way for Milo to
identify which bootloader exactly is required.  How about adding an entry

  boot_method    : ARC


  boot_method     : SGI

to /proc/cpuinfo so that Milo can autoconfigure completly for native

Sorry, no.  I've been running the latest kernels on Wayne's M700 with
success also.  So it can't be a M700 specific problem.  Could you send me
a more detailed description of your setup?
