The build rules to regenerate plural.c are conditional on "ifneq 
(no,$(BISON))".  So if you document a minimum version, you should also 
make the configure test check that version, so BISON is set to "no" if 
too-old bison is installed, and no attempt is made at rebuilding plural.c 
in that case.  (The documentation should also say it's only needed for 
regenerating intl/plural.c if changing intl/plural.y - it should be listed 
together with autoconf and gettext in that regard.)
