Makes sure that bison version is greater or equal to the version indicated. If true the shell commands in ACTION-IF-TRUE are executed. If not the shell commands in commands in ACTION-IF-TRUE are executed. If not the shell commands in ACTION-IF-FALSE are run. Note if $BISON is not set (for example by running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
AC_PATH_PROG([BISON],[bison]) AX_PROG_BISON_VERSION([3.0.2],[ ... ],[ ... ])
This will check to make sure that the bison you have is at least version 3.0.2 or greater.
NOTE: This macro uses the $BISON variable to perform the check.
