Subject: [PATCH] * 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.
