2003-12-03 Bruno Haible <bruno@clisp.org>
Upgrade from gettext-0.13.
+2004-01-15 Jim Meyering <jim@meyering.net>
+
+ Merge from coreutils.
+
+ * md5.h (rol) [__GNUC__ && __i386__]: Don't use `asm' code. These
+ days, gcc-3.x does better all by itself. Patch from Dean Gaudet:
+ http://mail.gnu.org/archive/html/bug-coreutils/2003-11/msg00144.html
+
+ * posixver.c (DEFAULT_POSIX2_VERSION): Use definition of new,
+ optional configure-time default.
+
+ * version-etc.c (version_etc_copyright): Update copyright date.
+
+ * xreadlink.c (xreadlink): Correct outdated comment.
+
+2004-01-15 Paul Eggert <eggert@twinsun.com>
+
+ Merge from coreutils.
+
+ * posixver.c: Include posixver.h.
+
+ * same.c: Include <stdbool.h>, <limits.h>.
+ (_POSIX_NAME_MAX): Define if not defined.
+ (MIN): New macro.
+ (same_name): If file names are silently truncated, report
+ that the file names are the same if they are the same after
+ the silent truncation.
+
+ * xstrtod.h (xstrtod): Accept an extra arg, specifying the
+ conversion function.
+ * xstrtod.c (xstrtod): Likewise. All callers changed to
+ include c-strtod.h and use c_strtod. Don't include stdlib.h; no
+ longer needed.
+
2004-01-14 Paul Eggert <eggert@twinsun.com>
* fnmatch_loop.c (ALLOCA_LIMIT): Remove macro, which collided
digest. */
