+   Some platforms have the multibyte functions such as mbsrtowcs but
+   are lacking the multitype type mbstate_t.  BeOS (unknown version)
+   and HP/UX 11.23 without _XOPEN_SOURCE=500 are like this.
+
+   We really need mbstate_t type to operate properly.  For example, see
+   compute_lcd_of_matches, where two mbstate_t's are active at the same
+   time.  So we require both the functions and the mbstate_t type in
+   order to enable multibyte support.  */
