    Provide missing description for our FLEXIBLE_ARRAY_MEMBER defines
    
    Apparently autoheader throws a tantrum if you say 'AC_DEFINE([a],
    [b])'.  Instead you must say 'AC_DEFINE([a], [b], [description of
    a])'.  We were running into this in our replacement definitions for
    FLEXIBLE_ARRAY_MEMBER, which were only getting built on autoconf
    versions before 2.61 -- and this made us stop working with those
    autoconf versinos.
    
    Fixes bug 2430; bugfix on 0.2.3.1-alpha.
