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