+ * manual/errno.texi (Error Codes): Added ECANCELED (118 for Hurd).
+ * sysdeps/mach/hurd/bits/errno.h: Regenerated.
+
+ * sysdeps/gnu/Versions: New file.
+ * sysdeps/unix/sysv/linux/Versions (libc: GLIBC_2.1): Remove
+ _sys_errlist; sys_errlist; _sys_nerr; sys_nerr; from here.
+ * sysdeps/gnu/Makefile ($(..)sysdeps/gnu/errlist-compat.c): New target.
+ ($(objpfx)errlist.d): Depend on $(..)sysdeps/gnu/errlist-compat.c.
+ * sysdeps/gnu/errlist.awk: Make output define _sys_errlist_internal
+ and _sys_nerr_internal instead of anything else. Make it include
+ "errlist-compat.c" if [!NOT_IN_libc && !ERRLIST_NO_COMPAT].
+ Make it emit some asm magic if [EMIT_ERR_MAX].
+ * sysdeps/gnu/errlist.c: Regenerated.
+ * sysdeps/gnu/errlist-compat.awk: New file.
+ * sysdeps/gnu/errlist-compat.c: New file (generated).
+ * sysdeps/mach/hurd/errlist.c (ERRLIST_NO_COMPAT): New macro.
+ (_sys_errlist_internal): Define this as a macro for _hurd_errlist.
+ (_sys_nerr_internal): Define this is a macro for _hurd_nerr.
+ (SYS_ERRLIST, SYS_NERR): Macros removed.
+ (sys_nerr, _sys_nerr): Remove these weak aliases.
+ * sysdeps/unix/sysv/linux/errlist.c: File removed.
+ * sysdeps/unix/sysv/linux/errlist.h: File removed.
