+       Always initialize terminal colorization string variables.
+       * build-aux/check.mk (am__tty_colors): Always initialize red, grn, etc.,
+       In case they're defined in the environment.

        Avoid test failure in non-srcdir build vs. the git tree.
        * tests/check.mk (vc_exe_in_TESTS): Run this test only in a
        srcdir build directory.  Reported by Andreas Schwab.
