+ * cp-tree.h (char_type_p): New function.
+ * decl.c (init_decl_processing): Don't initialize
+ signed_wchar_type_node or unsigned_wchar_type_node.
+ (complete_array_type): Handle brace-enclosed string-constants.
+ * rtti.c (emit_support_tinfos): Remove #if 0'd code.
+ * tree.c (char_type_p): New function.
+ * typeck2.c (digest_init): Use char_type_p.

2000-07-06 Nathan Sidwell <nathan@codesourcery.com>
* pt.c (tsubst): Don't layout type, if it's error_mark.
