 674 #         * configure.in, Makefile.in:  Avoid rebuilding "depend" as much.
 675 #         Avoid declaring Makefile dependencies, because GNU Make stupidly
 676 #         tries to update it if we do.
 677 #
 678 #         * coffread.c:  Revise for minor changes to bfd internal coff
 679 #         indexes.
 680 #
 681 #         * configure:  If -template= is given a relative path, make it
 682 #         absolute before recurring in subdirectories.
