Warning in TEST.EXE
  Problem:  No stack segment was found for the EXE file.
  Solution: This is possibly an error in your program.
            An EXE file, unlike a COM file, must internally setup
            its own stack if it has no stack segment.  To create a
            COM file, use the /c option of WarpLink.
