commit 7b037c095e31c2396d0a9b0e6356bc566ee4812f
Author: Zack Weinberg <zackw@panix.com>
Date:   Wed Nov 16 16:20:26 2016 -0500

    Clean up redundancies between string.h and strings.h.
    
    	* string/string.h [__USE_MISC]: Include strings.h.
    	(__bzero, bcmp, bcopy, bzero, index, rindex)
    	(strcasecmp, strncasecmp, strcasecmp_l, strncasecmp_l)
    	(ffs, ffsl, ffsll): Don't declare.
    
    	* string/strings.h: Do not suppress the file if string.h has
    	already been included.
    	(bcmp, bcopy, bzero, strcasecmp, strncasecmp): Add __nonnull
    	annotations.
    	(index, rindex): Define inline forwarders even if
    	__CORRECT_ISO_CPP_STRING_H_PROTO is defined.
    	(ffs): Use __attribute_const__.
    	(ffsl, ffsll): Declare here.
    	(strcasecmp_l, strncasecmp_l): Correct comments; these functions
    	have now been standardized.
    
    	* include/string.h (__bzero): Declare here.
