  21  *  a 16-bit environment with a fairly limited compiler.  It would make
  22  *  things much easier for me if this file isn't modified unnecessarily.
  23  *  In particular, please put any new or replacement functions somewhere
  24  *  else, and modify the makefile to use your version instead.
  25  *  Thanks.  Manuel
