+ * nss/nss_files/files-parse.c (parse_list): Set EOL from LINE if it
+ points within DATA->linebuffer; otherwise use all of DATA->linebuffer
+ itself, no need to skip past a NUL.
+
+ * nss/nsswitch.h (known_function): Comment fix.
+ * nss/nsswitch.c (nss_lookup_function): Rewritten using __tsearch
+ directly. Do the lookup and insertion with a single call, and fill in
+ the tree node afterwards if new.
+ (known_compare, nss_find_entry, nss_insert_entry): Functions removed.
+
+ * misc/sys/select.h: #define __need_timespec before <sys/time.h> incl.
+ (struct timeval): Add bodiless decl for scope.
+
+ * time/time.h (struct timespec): Rename members from `ts_*' to `tv_*'.
+ Move struct timespec defn outside [_TIME_H] so it can be got with
+ #define __need_timespec.
+
+ * time/sys/time.h (TIMEVAL_TO_TIMESPEC): Use `tv_*' instead of `ts_*'
+ for `struct timespec' member names.
+ (TIMESPEC_TO_TIMEVAL): Likewise.
+
+ * nss/Makefile (extra-libs-others): New variable.
+
+ * extra-lib.mk: Don't test for $($(lib)-no-lib-dep). Instead match
+ $(lib) in $(extra-libs-others).
+ * sunrpc/Makefile (extra-libs-others): New variable.
+ (librpcsvc-no-lib-dep): Variable removed.
+
* elf/rtld.c: Define RTLD_BOOTSTRAP before #include "dynamic-link.h".
* sysdeps/i386/dl-machine.h (elf_machine_rel): Remove weak decl for
_dl_rtld_map.
