+       unistr/u8-strchr: Fix several bugs.
+       * lib/unistr/u8-strchr.c (u8_strchr): Don't search beyond the end of
+       the string. When not found, return NULL, not a pointer near the end.
+
+       More tests for unistr/u8-strchr.
+       * tests/unistr/test-strchr.h (test_strchr): Renamed from main. Check
+       that the function does not read past the first occurrence of the byte
+       being searched.
+       * tests/unistr/test-u8-strchr.c (main): New function, with more tests.
+       * tests/unistr/test-u16-strchr.c (main): New function.
+       * tests/unistr/test-u32-strchr.c (main): New function.

+       posix-modules: Ignore backup files of documentation files.
+       * posix-modules: grep only through files named *.texi.

+       * doc/posix-functions/readlinkat.texi: Fix module name.

+       fchownat: Replace also when chown has the trailing slash bug.
+       * m4/openat.m4 (gl_FUNC_FCHOWNAT): Move the test of REPLACE_CHOWN
+       outside the gl_FUNC_FCHOWNAT_DEREF_BUG invocation. Fixes regression
+       introduced on 2010-04-10.
+       Reported by Rainer Tammer.

+
+       linkat: Work around AIX 7.1 bug.
+       * m4/linkat.m4 (gl_FUNC_LINKAT): Require AC_CANONICAL_HOST. Test
+       whether linkat handles trailing slash correctly. If not, replace linkat
+       and define LINKAT_TRAILING_SLASH_BUG.
+       * lib/linkat.c (rpl_linkat): If LINKAT_TRAILING_SLASH_BUG is defined,
+       check whether (fd1,file1) points to a directory if file1 or file2 ends
+       in a slash. Code taken from lib/link.c.
+       * doc/posix-functions/linkat.texi: Mention trailing slash bug.
+       Reported by Rainer Tammer.

        Correctly determine whether pow is available in libc on AIX 7 with xlc.
        * m4/mathfunc.m4 (gl_MATHFUNC): Actually use the 'funcptr' variable.
        This disables an xlc optimization that was causing wrong test results.
