Please read this page first:

We shouldn't try to get a copyright assignment for code written for 
another package.

About the license, I don't think the Mach license is incompatible 
against GPL. It just says:

+ * Carnegie Mellon requests users of this software to return to
+ *
+ *  Software Distribution Coordinator  or  
address@hidden
+ *  School of Computer Science
+ *  Carnegie Mellon University
+ *  Pittsburgh PA 15213-3890

They don't say "require" but it's simply a request. So, if my 
undestanding is correct, its legal impact should be void.

As I'm not a lawyer, I might be wrong. So I can ask address@hidden if 
you think I should confirm it.

The same as above.
