  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-1.26 because earlier versions generate a plural.c that doesn't
  dnl compile.
  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.
