For Debian Bug #206299: * automake.in ($configure_deps_greatest_timestamp, $output_deps_greatest_timestamp): New variables. (initialize_per_input): Reset $output_deps_greatest_timestamp. (scan_autoconf_traces, scan_autoconf_files, read_am_file): Update $configure_deps_greatest_timestamp and $output_deps_greatest_timestamp (generate_makefile): Rewrite the logic to decide whether to rewrite the output. Move the leading dup_channel_setup and trailing drop_channel_setup to MAIN, so that drop_channel_setup is executed for all exit paths. * tests/aclocal7.test: Update to check for $AUTOMAKE --no-force * tests/distcom6.test: New file. Report from Scott James Remnant. * tests/Makefile.am (TESTS): Add distcom6.test.
