        * trans-common.c (get_init_field): New function.
        (create_common): Call get_init_field for overlapping
        initializers in equivalence blocks.
        * resolve.c (resolve_equivalence_derived, resolve_equivalence):
        Remove constraints on initializers in equivalence blocks.
        * target-memory.c (expr_to_char, gfc_merge_initializers):
        New functions.
        (encode_derived): Add the bit offset to the byte offset to get
        the total offset to the field.
        * target-memory.h : Add prototype for gfc_merge_initializers.
