+       Make chdir-safer.c slightly safer.
+       * lib/chdir-safer.c (chdir_no_follow): Test HAVE_WORKING_O_NOFOLLOW,
+       not O_NOFOLLOW, in case the latter is nonzero and open ignores it.
+
+       Avoid compile failure on systems without ELOOP (like mingw).
+       * lib/chdir-safer.c (ELOOP): Define if not already defined.
+       Reported by Bruno Haible.

+
+       * lib/unilbrk/ulc-common.c: Include c-strcaseeq.h instead of streq.h.
+       (is_utf8_encoding): Use a case-insensitive comparison.
+       * modules/unilbrk/ulc-common (Depends-on): Add c-strcaseeq. Remove
+       streq.
