6397 scope_freelist; initialize scope->depth and check for overflow.
6398 (poplevel): Rename to pop_scope; totally rewritten for new bindings
6400 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
6401 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
6402 Improve some commentary. Adjust handling of forward parm decls.
6403 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
6404 Preserve C_DECL_IN_EXTERNAL_SCOPE.
6405 (warn_if_shadowing): Correct indentation. Improve diagnostics.

6408 Eliminate the copy_node call.

6425 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
6426 First scope pushed is the external scope, not the global scope.

6470 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
6471 correct loop over multiple translation units; call fatal_error if
6472 requested to compile more than one file at once. (This disables
6473 IMA temporarily - an up-front error being preferable to a crash.)

11259 (_cpp_lex_direct): Use linemap_position_for_column.
11260 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
