	* Versions.def: Add versions for ld.so.
	* csu/Versions: Remove __libc_stack_end here.
	* elf/Versions: Split libc definitions in libc and ld.so definitions.
	* elf/Makefile (ld-map): Change to ld.so.map.
	* scripts/versions.awk: Recognize dot in library names.

	* ctype/ctype.h: Remove definitions of __tolower and __toupper.
	Don't use __tolower and __toupper in inline functions.
	Add optimizing macros for tolower and toupper.
	* ctype/ctype-extn.c (_tolower): Don't use __tolower.
	(_toupper): Don't use __toupper.
	* ctype/ctype.c (tolower): Don't use __tolower.
	(toupper): Don't use toupper.

	* nscd/cache.c (prune_cache): Correct printing of debugging messages.

	* resolv/Versions (libresolv): Export __ns_name_unpack and
	__ns_name_ntop.
	* resolv/res_comp.c: Rename ns_name_unpack to __ns_name_unpack and
	make it global.  Change all users.  Similar for ns_name_ntop.
	* resolv/nss_dns/dns-host.c: Don't use dn_expand when extracting in
	user-provided buffer.  Use __ns_name_unpack and __ns_name_ntop
	directly to detect too small buffer.
	* stdio-common/Makefile (tests): Add scanf12.
	* stdio-common/scanf12.c: New file.
	* stdio-common/scanf12.input: New file.
	* stdio-common/vfscanf.c (__vfscanf): Handle +/- at beginning of
	floating-point correctly if the number is invalid.
	* stdio-common/vfscanf.c: Don't use non-reentrant multibyte conversion
	* stdio-common/printf_fphex.c: Likewise.
	* stdio-common/vfprintf.c: Likewise.
See ChangeLog.9 for earlier changes.
