   dnl intl/plural.c is generated from intl/plural.y. It requires bison,
   dnl because plural.y uses bison specific features. It requires at least
-  dnl bison-2.7 for %define api.pure.
+  dnl bison-3.0 for %precedence.
   dnl bison is only needed for the maintainer (who touches plural.y). But in
   dnl order to avoid separate Makefiles or --enable-maintainer-mode, we put
   dnl the rule in general Makefile. Now, some people carelessly touch the
   dnl files or have a broken "make" program, hence the plural.c rule will
   dnl sometimes fire. To avoid an error, defines BISON to ":" if it is not
   dnl present or too old.
