 650 # More name changing
 651 #
 652 # Revision 1.62  1991/10/24  11:59:03  rich
 653 # add null definitions for makefile_frag_foo
 654 #
 655 # Revision 1.61  1991/10/24  00:23:59  hgs
 656 # Allow for using tmake-sun4
 657 #
 658 # Revision 1.60  1991/10/23  21:48:28  rich
 659 # Makefiles should include the makefile frag names even if the makefile
 660 # frag doesn't exist in *this* directory.  Otherwise we inherit the
 661 # variable setting from our parent Makefile.
 662 #
 663 # Revision 1.59  1991/10/16  19:53:31  gnu
 664 # Update for SCO problems.
 665 #
 666 # * Fix "Larry Wall kludge" line so it works.  If this script is run by csh,
 667 # it will complain, feed itself to sh, and complain some more.  But will work.
 668 #
 669 # * Use <14 char file names in /tmp.
 670 #
 671 # Revision 1.58  1991/10/16  06:12:52  rich
 672 # Two small bugs.  First, single quoted sed line doesn't need to quote
 673 # '$'.  Second, use quotes around the hereis document trigger in order
 674 # to quote the entire contents of the hereis document.
 675 #
 676 # Revision 1.57  1991/10/11  05:31:05  gnu
 677 # Simplify "Using" message code.  Put the message that configure prints
 678 # (or suppresses) into the config.status file as a comment.
 679 #
 680 # Revision 1.56  1991/10/10  05:01:47  rich
 681 # Remove the set -e but protect the recusion call.
 682 #
 683 # Revision 1.55  1991/10/10  04:57:23  rich
 684 # * Die when sub-configure's do.
 685 # * get the makefile building message line correct.
 686 # * set -e
 687 #
 688 # Revision 1.54  1991/10/10  01:04:42  rich
 689 # Backed out the "/bin/sh config.sub" change.  Fails when config.sub was
 690 # on PATH.
 691 #
 692 # Revision 1.53  1991/10/10  00:38:08  rich
 693 # Call config.sub as "/bin/sh config.sub" instead of directly.  This
 694 # protects us from the case where config.sub isn't executable.
 695 #
 696 # Revision 1.52  1991/10/09  00:48:26  rich
 697 # Another patch from jim.

 708 # Revision 1.48  1991/10/02  13:17:28  rich

 713 # * +objdir
 714 #
 715 # Revision 1.46  1991/10/02  06:29:53  rich
 716 # Added +site=foo option for naming site specific Makefile fragments.
 717 #
 718 # Revision 1.45  1991/10/02  06:15:13  rich
 719 # Removed +f option.  Used to stand for +forcesubdirs which is now
 720 # called +subdirs.
 721 #
 722 # Revision 1.44  1991/10/02  06:02:35  rich
