* gdbtypes.c (finish_cv_type): New function.

(check_typedef): Remove ``register'' keyword from argument.
        Preserve const and volatile attributes across filling in
        opaque types.
        * gdbtypes.h (finish_cv_type): Add prototype.

        * hp-symtab-read.c (hpread_read_struct_type): Call finish_cv_type.
        * stabsread.c (read_struct_type): Likewise.
        * dwarf2read.c (read_structure_scope): Likewise.  Remove redundant
        assignment to die->type.
