+ * hurd/hurdstartup.c (_hurd_startup): Use new
+ exec_startup_get_info RPC from exec_startup.defs
+ in place of old exec_startup from exec.defs. Remove kludge to
+ guess user entry and phdr locations, since the new RPC gives us
+ that info.
+
* stdio/stdio.h (sys_errlist, _sys_errlist): Declare const.
+ * sysdeps/generic/_strerror.c: Undo last change.
* sysdeps/unix/sysv/linux/stat.c: New file.
* sysdeps/unix/sysv/linux/fstat.c: New file.
