One side-effect of this change is that "make check" now works even if you put "." early in your shell's search PATH (don't do that!). Remove all test-related Makefile.am files, except those generated by mk-script. Instead, tests/Makefile.am now lists not only the tests directly under tests/, but also those in tests/*/ that are not generated by mk-script, e.g., cp/abuse, cp/acl, mv/i-1, etc. A lot of these changes are like this: -. $srcdir/../lang-default +. $top_srcdir/tests/lang-default -. $srcdir/../test-lib.sh +. $top_srcdir/tests/test-lib.sh * configure.ac (AC_CONFIG_FILES): Remove corresponding Makefiles. * tests/check.mk (vc_exe_in_TESTS): Relax syntax requirements. * tests/rwx-to-mode: Remove file. Rewritten as... * tests/test-lib.sh (rwx_to_mode_): ...this new function. * tests/Makefile.am (EXTRA_DIST): Remove rwx-to-mode. (SUBDIRS): Remove each dir with a removed Makefile.am. (EXTRA_DIST): Add $(TESTS). (TESTS): Add over 300 entries.
