+ Import filemode module from gnulib.
+ * .bzrignore: Add lib/sys/.
+ * Makefile.in (GNULIB_MODULES): Add filemode.
+ * lib/Makefile.am (MOSTLYCLEANDIRS): New macro.
+ * lib/filemode.c: Renamed from src/filemode.c and regenerated
+ from gnulib. This adds support for some more file types, e.g.,
+ Cray DMF migrated files.
+ * lisp/emacs-lisp/find-gc.el (find-gc-source-files): Remove filemode.c.
+ * lib/filemode.h, lib/sys_stat.in.h, m4/filemode.m4, m4/st_dm_mode.m4:
+ * m4/sys_stat_h.m4: New files, generated from gnulib.
+ * aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
+ Regenerate.
+
2011-02-20 Eli Zaretskii <address@hidden>
* lib/makefile.w32-in ($(BLD)/md5.$(O)): Don't depend on
