mini-os compile error

["Michael Levenhagen" <mjleven@sandia.gov>]

I just downloaded xen-2.0.7-src.tgz and when I try and compile mini-os I 
get the following errors

mjleven@sacp957:~/xen-2.0/extras/mini-os> make

I can get around this by changing the comment symbols to /*  */.

but then I get

I can't find EVENTS_MASTER_ENABLE_BIT defined anywhere.

I'm running on a SUSE 9.2 Pro. distro.

I can build xen, tools and linux26 just fine.

What am I doing wrong?

thanks

PS. I've tried unstable and I get a completely different compile failure.
