The main reason why it didn't work was because he was creating a 400k+ array 
on the stack to act as a pseudo-heap.  I suggested to him that he should move 
it out into the real heap using "Marshal.AllocHGlobal" instead.

There were also some problems processing forwardly-defined ".data" 
declarations and global variables in ".data" areas, which would have also 
been easy to fix with some small changes to his code.  I haven't heard back 
from him since (that was Jan).

He's using a similar approach to egcs-jvm.  See the pnet FAQ for a description 
of why this isn't a good way to port gcc to a stack machine.
