+Subject: [PATCH] Fix build with Leptonica >=1.83
+
+From leptonica 1.83 release notes:
+ * Use stdatomic.h to make cloning string safe. Remove all *GetRefcount() and *ChangeRefcount() accessors.
+ * Remove information about fields in many structs from the public interface allheaders.h, instead putting them in internal files pix_internal.h, array_internal.h and ccbord_internal.h.
