Require bison 2.7 or newer for regenerating intl/plural.y
The merge of the latest gettext code introduced changes to the yacc parser source that are incompatible with versions of bison older than 2.7. Add a configure check for the appropriate versions and document the requirement in INSTALL. ChangeLog: 2014-12-22 Will Newton <will.newton@linaro.org> * manual/install.texi: Document that we require bison 2.7 or above. * INSTALL: Regenerate. * configure.ac: Use AC_CHECK_PROG_VER instead of AC_PATH_PROG when checking for bison and check for version 2.7 or above. * configure: Regenerate.
