| 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-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. |
