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. | |
