    2008-10-10  Paolo Bonzini  <address@hidden>
    
        * m4sugar/m4sh.m4 (_AS_MKDIR_P): New, from AS_MKDIR_P.  Adjust
        meaning of as_mkdir_p to be `false' or a full `mkdir -p' command.
        (AS_MKDIR_P): Just dispatch to as_func_mkdir_p.
        (_AS_PREPARE): Define shell functions.
        (_AS_MKDIR_P_PREPARE): Set as_mkdir_p according to the above change.
        Define shell functions.
