7378 (pushlevel): Ignore argument. Do not push another binding
7379 level on the transition from the parameters to the top level
7380 of the function body; just tweak the flags and proceed.

7430 (poplevel): Delete #if 0 block. Make externals invisible
7431 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7432 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7433 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7434 (duplicate-decls): For real parm decl after a forward decl,
7435 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7436 foo(...) { } with only a warning. Say whether a previous
7437 declaration was implicit.

7439 local-over-local. Clarify comments.
7440 (pushdecl): Rewritten. There is no longer a distinction
7441 between global and local symbol values; they're all
7442 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7443 DECL_EXTERNAL decls, and use any_external_decl to check
7444 against previous externals. Kill #if 0 blocks. Don't
7445 tolerate error_mark_node being NULL.

7447 Objective C (the only user) needs.
7448 (pushdecl_function_level): New function.
7449 (implicitly_declare): Create ordinary decls with

7465 from build_external_ref.
