Yes, gnulib declares these functions in <string.h> since 2007-01-26. It was probably an oversight. Care to provide a patch that moves that out to a substitute for <strings.h>? (The substitute does not need to be complete. We don't care about the functions that are marked 'LEGACY' in POSIX.) > I don't know the best thing to do.

Yes, a look at doc/functions/strncasecmp.texi tells you that this function is hardly useful since it does not work reasonably in multibyte-locales, which are the majority of locales nowadays. If you need a locale-dependent case comparison, use the mbs* functions; if you need a locale-independent case comparison that considers only ASCII upper/lower letters, use the c-str* functions.
