+       regcomp.c: make non-_LIBC implementation of build_range_exp consistent
+       The _LIBC implementation of build_range_exp correctly honors the
+       RE_NO_EMPTY_RANGES flag when checking for reversed range endpoints.
+       However, the non-_LIBC implementation would ignore that syntax-bit
+       flag and return REG_ERANGE unconditionally.
+       This change makes it honor that flag.
+       * lib/regcomp.c (build_range_exp) [!_LIBC]: Add a parameter: "syntax".
+       Make two pointer parameters "const".
+       Use "syntax" bits in order to honor RE_NO_EMPTY_RANGES.
+       (parse_bracket_exp): Update caller.
+
+       regex.m4: correct the reversed range endpoint ([b-a]) test
+       * m4/regex.m4: When requiring that [b-a] evoke failure,
+       use RE_NO_EMPTY_RANGES.  This makes this entire configure-time
+       test pass once again for x86-based systems.

+       scandir: Fix link error on Solaris 8.
+       * lib/scandir.c (_D_EXACT_NAMLEN, _D_ALLOC_NAMLEN): New fallback

+       getusershell: Fix documentation.
+       * doc/glibc-functions/endusershell.texi: Refer to the getusershell
+       module.
+       * doc/glibc-functions/setusershell.texi: Likewise.

+       getusershell: Provide declaration, missing on Solaris 9.

+       also if HAVE_GETUSERSHELL && !HAVE_DECL_GETUSERSHELL.
+       * m4/getusershell.m4 (gl_FUNC_GETUSERSHELL): When the function exists,
+       check whether it is declared. Set HAVE_DECL_GETUSERSHELL.
+       * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize
+       HAVE_DECL_GETUSERSHELL, not HAVE_GETUSERSHELL.
+       * modules/unistd (Makefile.am): Substitute HAVE_DECL_GETUSERSHELL, not
+       HAVE_GETUSERSHELL.

+       exists and is fine.
+       * m4/wctype_h.m4 (gl_WCTYPE_H): Also check whether iswcntrl exists.
+       * modules/wctype (Makefile.am): Substitute HAVE_ISWBLANK.
+       * tests/test-wctype.c (main): Re-enable the iswblank tests.
