30378 * c-common.c (c_common_nodes_and_builtins): Since variants of
30379 void_type_node get built before it is given a name, we need to
30380 give those variants the name, too.

30386 * stor-layout.c (layout_type): When we don't know the
30387 alignment of a type for which we're building an array, we end up
30388 guessing wrong, so make the type require structural equality.

30390 own canonical type.
30391 (build_type_attribute_qual_variant): When building an attribute
30392 variant, its canonical type is the non-attribute variant. However,
30393 if the attributes are target-dependent and they differ, we need to
30394 use structural equality checks for this type.
30395 (build_qualified_type): A qualified type is not equivalent to its
30396 unqualified variant; set the canonical type appropriately.
30397 (build_distinct_type_copy): When building a distinct type from
30398 another type, the new type is its own canonical type.
30399 (build_variant_type_copy): When building a new type variant, we
30400 assume that it is equivalent to the original type.
30401 (build_pointer_type_for_mode): When building a pointer type, also
30402 build a canonical type pointer.
30403 (build_reference_type_for_mode): When building a reference type,
30404 also build a canonical type reference.
30405 (build_index_type): When we can't hash an index type (e.g.,
30406 because its maximum value is negative), the index type requires
30407 structural equality tests.
30408 (build_array_type): Build the canonical form of an array type.
30409 (build_function_type): Function types require structural equality,
30410 because they contain default arguments, attributes, etc.
