 and wcsnrtombs.c. 	* libc/stdlib/Makefile.in: Regenerate. 	*
 libc/stdlib/mbsnrtowcs.c: New file, implementing _mbsnrtowcs_r 	and
 mbsnrtowcs.  Document mbsnrtowcs and mbsrtowcs. 	*
 libc/stdlib/mbsrtowcs.c (_mbsrtowcs_r): Just call _mbsnrtowcs_r. 
 (mbsrtowcs): Ditto. 	* libc/stdlib/wcsnrtombs.c: New file, implementing
 _wcsnrtombs_r 	and wcsnrtombs.  Document wcsrtombs and wcsnrtombs. 	*
 libc/stdlib/wcsrtombs.c (_wcsrtombs_r): Just call _wcsnrtombs_r.
