+
+ Work around an fchownat bug in glibc-2.4:
+ http://lists.ubuntu.com/archives/ubuntu-users/2006-September/093218.html
+ This bug would cause "chown -RP ... DIR" to follow symlinks in DIR,
+ in spite of the -P option.
+ * m4/openat.m4 (gl_FUNC_FCHOWNAT, gl_FUNC_FCHOWNAT_DEREF_BUG):
+ New macros.
+ (gl_PREREQ_OPENAT): Require gl_FUNC_FCHOWNAT.
+ * modules/openat (Files): Add lib/fchownat.c.
+ * lib/openat.c (fchownat): Don't define here. Move to...
+ * lib/fchownat.c: ...this new file.

+
+ Fix bug reported by Bruno Haible in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00228.html>
+ where quotearg.c didn't compile on Mac OS X 10.2 because it
+ lacks <wchar.h> and wint_t.
+ * lib/wctype_.h (__wctype_wint_t): New type.
+ Include <stdio.h>, <time.h>, <wchar.h> only if HAVE_WINT_T.
+ (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph):
+ (iswlower, iswprint, iswpunct, iswspace, iswupper, ixwxdigit):
+ Arg is now of type __wctype_wint_t, not wint_t.
+ * m4/wctype.m4 (gl_WCTYPE_H): Require gt_TYPE_WINT_T, and
+ substitute HAVE_WINT_T.
+ * modules/wctype (Files): Add m4/wint_t.m4.
+ (wctype.h): Substitute HAVE_WINT_T.

+
+ * lib/safe-read.h [C++]: Wrap declarations in extern "C".
+
+2006-12-23 Bruno Haible <bruno@clisp.org>
+
+ * lib/canonicalize-lgpl.c (__realpath): Test HAVE_READLINK instead of
+ S_ISLNK.
+ Needed because gnulib's sys/stat.h replacement defines S_ISLNK on
+ mingw.
+
+2006-12-22 Bruno Haible <bruno@clisp.org>
+
+ * lib/copy-file.c: Include acl.h.
+ (copy_file_preserving) [USE_ACL]: Use copy_acl instead of chmod.
+ Close the file descriptors only after being done with copy_acl.
+ * modules/copy-file (Depends-on): Add acl.
+
+2006-12-22 Bruno Haible <bruno@clisp.org>
+
+ * gnulib-tool (SED): New variable.
+ Use $SED instead of sed everywhere.

+
+ * modules/no-c++: New file.
+ * m4/no-c++.m4: New file.
+ * MODULES.html.sh (Support for building libraries and executables):
+ Add no-c++.

+
+ * m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf.
+ Include <limits.h>, and use its INT_MAX to rewrite the
+ j loop so that it does not overflow 'int'. Problem reported by
+ Ralf Wildenhues in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
+ Play it safe by shifting left by 1 rather than multiplying by 2,
+ as GCC is less likely to optimize this away when the value
+ is signed (when it assumes overflow leads to undefined behavior).
+ Also, don't assume time_t uses two's complement.

+
+ * MODULES.html.sh: New module wctype.
+ * lib/wctype_.h, m4/wctype.m4, modules/wctype: New files.
+ * lib/fnmatch.c: Don't bother to include <wchar.h> before
+ <wctype.h>, since the new wctype module should fix this.
+ * lib/quotearg.c: Include <wctype.h> unconditionally, since
+ the wctype module should arrange for it.
+ * lib/regex_internal.h: Likewise.
+ * m4/quotearg.m4 (gl_QUOTEARG): Don't check for wctype.h or iswprint,
+ since the wctype module should handle this now.
+ * m4/regex.m4 (gl_PREREQ_REGEX): Don't check for wctype.h.
+ * modules/fnmatch (Depends-on): Add wctype.
+ * modules/quotearg (Depends-on): Likewise.
+ * modules/regex (Depends-on): Likewise.
