        !             5: # libc includes both real and fake versions of _dtefg() (floating point output)
        !             6: # and of _finish() (close open FILEs).
        !             7: # If a program requires floating point output, the "-f" flag to /bin/cc
        !             8: # produces an "-u _dtefg_" argument to /bin/ld, forcing the link to include
        !             9: # the real floating point output routine from _dtefg.o.
        !            10: # Otherwise, /bin/ld resolves the reference to _dtefg() in vfprintf.o with
        !            11: # the much smaller fake floating point output routine from _fdtefg.o.
        !            12: # To avoid linking in extra stdio overhead when not required,
        !            13: # libc.a should contain _fp.o, _finit.o, exit.o and _finish.o, in that order,
        !            14: # after stdio objects from $(OBJ) and from the machine-dependent subdirectory,
        !            15: # If a program uses stdio, /bin/ld will link in _finit.o;
        !            16: # finit.o defines the real _finish() which closes all open files for exit().
        !            17: # If a program does not use stdio, /bin/ld will link in exit.o but not _finit.o;
        !            18: # then it resolves the _finish() reference in exit() with the fake _finish.o,
