                Options for the f77 Compiler and the Loader

     See "man f77" and "man ld" for a complete list of options.  These
     are the most commonly used options:

             -C      generate execution time subscript bounds checking
             -O      optimize (somewhat) the object code
             -w      suppress all warning messages
             -w66    suppress warning messages regarding Fortran 66
                             compatibility
             -c      compile only; don't load
             -g      save the symbol table for the symbolic debugger, dbx,
                             load special subroutines in case dbx is used
                             interactively, and cause core to be dumped
                             on errors
             -p      generate code to perform execution time profiling
                             by the 'prof' command
             -pg     generate code to perform execution time profiling
                             by the 'gprof' command - this is more
                             extensive than -p and 'prof'
             -q      suppress printing file and program unit names during
                             compilation
             -o fn   save the executable in 'fn' instead of in 'a.out'
             -M      load map: the loader prints out each file scanned
                             and which files are loaded from archives
             -l scan the indicated system library, e.g. -lf77plot
                             causes /usr/lib/libf77plot.a, the f77 graphics
                             interface library, to be scanned during loading
                             and any needed object files in that library
                             are loaded

     The -C, -O, -w, -w66, -q, and -c options are directed to the com-
     piler; -l, -o, and -M are directed to the loader, and -g, -p, -pg
     must be specified to both.  Thus:

             f77 -c -g -p -C prog.f
             f77    -g -p    prog.o -lf77plot -o myprog

     is equivalent to:

             f77 -g -p -C prog.f -lf77plot -o myprog
