	OK, I finally ported my game to DJGPP, and it compiled, and
made an executable.  When I run the executable, though it crashes, and
the SYMIFY output looks like this:

	I look at the line it refers to and all it is a declaration of
a temporary int to equal an element in an array like
  int temp=map[desty*320+destx];  
where desty and destx are just coords.  Map is a 64K array.  What
possible error could this be?  I thought it might be some kind of
stack error so I used stubedit and gave it a 2 meg stack but it still
had the same error.  Any help would be appreciated.
