        How about exec? Olin Shivers writes:

        "Unfortunately, the Unix exec(2) syscall's support for scripts
      is not very general or well-designed.  It will not handle
      multiple arguments; the #! line is usually required to contain
      no more than 32 characters; it is not recursive.  If these
      restrictions are violated, most Unix systems will not provide
      accurate error reporting, but either fail silently, or simply
      incorrectly implement the desired function.  These are the facts
      of Unix life".

        Are they the facts of GNU life too?


        Paul.
