decl.c (cplus_expand_expr_stmt): Promote warning about naked member function reference to error.
* decl.c (cplus_expand_expr_stmt): Promote warning about naked
member function reference to error.
* cvt.c (ocp_convert): Complain about converting an overloaded
function to void.
* init.c (build_offset_ref): Just return a lone static member
function.
* decl.c (cp_finish_decl): Only complain about real CONSTRUCTORs,
not internal ones.
* typeck.c (build_binary_op_nodefault): Improve error handling.
* decl.c (grokfndecl): Complain about making 'main' a template.
* typeck.c (string_conv_p): Don't convert from wchar_t[] to char*.
* call.c (build_method_call): Handle a BIT_NOT_EXPR around a
TYPE_DECL in a template.
* typeck2.c (my_friendly_abort): Add URL in the other case, too.
