        * tree-complex.c (vector_inner_type): New variable moved from
        build_word_mode_vector_type.
        (vector_last_type): Likewise.
        (vector_last_nunits): Likewise.
        (build_word_mode_vector_type): Use the new variables.
        * Makefile.in (tree-complex.o): Add gt-tree-complex.h $(GGC_H).
        (GTFILES): Add tree-complex.c.
        (gt-tree-complex.h): New rule, add it to the rest of the gt-* rules.
