commit cc8623f196cd5d1c82573b34cb3a6a56f712790a
Author: Will Newton <will.newton@linaro.org>
Date:   Thu Dec 11 17:27:34 2014 +0000

    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.
