I found that parent_max variable can be not used by code in macro 
SET_MINMAX_SET_BIT if release mode is used.  That results in generation 
of an unnecessary warning.

The following patch removes the warning and is committed as obvious.

         * ira-conflicts.c (build_object_conflicts): Add unused attribute
         to parent_max.
