Whenever I make a major update in my installed kernel I usually try to
get this sample program to work ... just out of pure curiosity right
now.  It has gone through a few changes over the years.

I've included below:
- The source code
- the error display
- the Makefile

I resolved several of the original include errors just by fixing
symbolic links in /usr/include/ BUT in this last one (or so) I'm not
sure which of the several "mach" directories should be used.

Could someone point out the proper modification(s) that should be made
to this simple user space module to get it to work?  Assuming of
course that its not some kind of major re-write, I am expecting a
sympolic link or 2 must be fixed or an include.

Thanks in advance!

PS No, this is not a school project, I just have some time on my hands
and I'm trying out some LJ code!   :-)
