The memory map under TPW is quite different.  I don't have the manuals
at home, so I may get this wrong, but I think they've put the stack and
near heap into the same segment as static data and constants.  I can't
remember what the near heap is used for, so I don't know how small you 
can safely make it, but I think the manual discusses it.
