 627 # Makefiles should include the makefile frag names even if the makefile
 628 # frag doesn't exist in *this* directory.  Otherwise we inherit the
 629 # variable setting from our parent Makefile.
 630 #
 631 # Revision 1.59  1991/10/16  19:53:31  gnu
 632 # Update for SCO problems.
 633 #
 634 # * Fix "Larry Wall kludge" line so it works.  If this script is run by csh,
 635 # it will complain, feed itself to sh, and complain some more.  But will work.
 636 #
 637 # * Use <14 char file names in /tmp.
 638 #
 639 # Revision 1.58  1991/10/16  06:12:52  rich
 640 # Two small bugs.  First, single quoted sed line doesn't need to quote
 641 # '$'.  Second, use quotes around the hereis document trigger in order
 642 # to quote the entire contents of the hereis document.
 643 #
 644 # Revision 1.57  1991/10/11  05:31:05  gnu
 645 # Simplify "Using" message code.  Put the message that configure prints
 646 # (or suppresses) into the config.status file as a comment.
 647 #
 648 # Revision 1.56  1991/10/10  05:01:47  rich
 649 # Remove the set -e but protect the recusion call.
 650 #
 651 # Revision 1.55  1991/10/10  04:57:23  rich
 652 # * Die when sub-configure's do.
 653 # * get the makefile building message line correct.
 654 # * set -e
 655 #
 656 # Revision 1.54  1991/10/10  01:04:42  rich
 657 # Backed out the "/bin/sh config.sub" change.  Fails when config.sub was
 658 # on PATH.
 659 #
 660 # Revision 1.53  1991/10/10  00:38:08  rich
 661 # Call config.sub as "/bin/sh config.sub" instead of directly.  This
 662 # protects us from the case where config.sub isn't executable.
 663 #
 664 # Revision 1.52  1991/10/09  00:48:26  rich
 665 # Another patch from jim.
 666 #
 667 # Revision 1.51  1991/10/08  06:07:58  wilson
 668 # Fix bug in smake- file code.

 670 # Revision 1.50  1991/10/04  23:49:37  rich
 671 # Per's patch for my config.sub botch.
 672 #
 673 # Revision 1.49  1991/10/04  22:52:09  rich
 674 # Use john's heuristic for finding ourselves.  kinda like hare krishna.
 675 #
 676 # Revision 1.48  1991/10/02  13:17:28  rich
 677 # take out the set -e for now
 678 #
 679 # Revision 1.47  1991/10/02  10:02:23  rich
 680 # * temporary files in TMPDIR
 681 # * +objdir
 682 #
 683 # Revision 1.46  1991/10/02  06:29:53  rich
 684 # Added +site=foo option for naming site specific Makefile fragments.
 685 #
 686 # Revision 1.45  1991/10/02  06:15:13  rich
 687 # Removed +f option.  Used to stand for +forcesubdirs which is now
 688 # called +subdirs.
 689 #
 690 # Revision 1.44  1991/10/02  06:02:35  rich
