7374 (pushlevel): Ignore argument. Do not push another binding
7375 level on the transition from the parameters to the top level
7376 of the function body; just tweak the flags and proceed.

7424 (c_print_identifier): Update to match changes to struct
7426 (poplevel): Delete #if 0 block. Make externals invisible
7427 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7428 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7429 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7430 (duplicate-decls): For real parm decl after a forward decl,
7431 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7432 foo(...) { } with only a warning. Say whether a previous
7433 declaration was implicit.
7434 (warn_if_shadowing): Now handles all shadowing, not just
7435 local-over-local. Clarify comments.
7436 (pushdecl): Rewritten. There is no longer a distinction
7437 between global and local symbol values; they're all
7438 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7439 DECL_EXTERNAL decls, and use any_external_decl to check
7440 against previous externals. Kill #if 0 blocks. Don't
7441 tolerate error_mark_node being NULL.

7443 Objective C (the only user) needs.
7444 (pushdecl_function_level): New function.
7445 (implicitly_declare): Create ordinary decls with

7461 from build_external_ref.

7466 IDENTIFIER_GLOBAL_VALUE.
