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.
