Robert's enhancements to `symlink' aren't documented.  Here:

  MSDOS doesn't support symbolic links.  However, DJGPP supports
  ``symlinks'' to DJGPP programs.  This function simulates a symlink
  between two @file{.exe} files in the DJGPP style.  It creates a program
! whose name is given by @var{*new} which, when run, will actually execute
! the program @var{*exists} passing it @var{*new} in @code{argv[0]} (some
! programs change their behavior depending on what's passed in
! @code{argv[0]}).  The file referred to by @var{exists} doesn't really
! have to exist when this function is called.  Both @var{*new} and
! @var{*exists} can point to a name with or without the @file{.exe}
! extension.
  
! Note that both @var{*exists} and @var{*new} must reside in the same
  directory (this is a restriction of the DJGPP ``symlinks''); the
  function will fail and set @code{errno} to @code{EXDEV} if they aren't.
- Also note that this function does nothing to ensure that @var{*exists}
- is actually a DJGPP program.
  
  This functions runs the @samp{stubify} and @samp{stubedit} programs, so
  they should be somewhere on your @samp{PATH} for the function to
