6075 (pushlevel): Ignore argument. Do not push another binding
6076 level on the transition from the parameters to the top level
6077 of the function body; just tweak the flags and proceed.

6125 (c_print_identifier): Update to match changes to struct
6127 (poplevel): Delete #if 0 block. Make externals invisible
6128 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6129 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6130 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6131 (duplicate-decls): For real parm decl after a forward decl,
6132 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6133 foo(...) { } with only a warning. Say whether a previous
6134 declaration was implicit.
6135 (warn_if_shadowing): Now handles all shadowing, not just
6136 local-over-local. Clarify comments.
6137 (pushdecl): Rewritten. There is no longer a distinction
6138 between global and local symbol values; they're all
6139 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6140 DECL_EXTERNAL decls, and use any_external_decl to check
6141 against previous externals. Kill #if 0 blocks. Don't
6142 tolerate error_mark_node being NULL.

6144 Objective C (the only user) needs.
6145 (pushdecl_function_level): New function.
6146 (implicitly_declare): Create ordinary decls with

6162 from build_external_ref.

6167 IDENTIFIER_GLOBAL_VALUE.
