2280 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
2281 field as well as the backend_decl.
2282 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2283 derived types that are not vtypes. Components with caf_token
2284 attribute are pvoid types. For a component requiring it, find
2285 the caf_token field and have the component token field point to
