	  ( | mode ); | 
 When called from Fortran, this routine has the same effect as
    when invoked from C (see plparseopts) except that the argument list
    just contains the parsing mode and the Fortran system routines
    iargc and getarg
    are used internally to obtain the number of arguments and
    argument values.  (Note, during configuration, the user's
    Fortran compiler
    is checked to see whether it supports
    iargc and getarg.  If it
    does not, the Fortran plparseopts simply writes a warning message
    and returns.
