If NTVDM is crashing, the easiest thing to do is to patch NTVDM.EXE if
you are allowed to fix the box.  My Win2000 box is pretty stable with
the patch below.  The NTVDM for Windows 2000 has a bug (as does XP RC1) 
which aborts when you nest DPMI images.  make/gcc/cc1 is a perfect
example of nesting.

Included below are binary diffs to NTVDM.EXE to work around the bug in
Windows 2000.  Eventually I'll provide an executable to do it.  You must
either disable file protection or also patch the ones in dllcache.
