7408 (pushlevel): Ignore argument. Do not push another binding
7409 level on the transition from the parameters to the top level
7410 of the function body; just tweak the flags and proceed.

7460 (poplevel): Delete #if 0 block. Make externals invisible
7461 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7462 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7463 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7464 (duplicate-decls): For real parm decl after a forward decl,
7465 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

7469 local-over-local. Clarify comments.
7470 (pushdecl): Rewritten. There is no longer a distinction
7471 between global and local symbol values; they're all
7472 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7473 DECL_EXTERNAL decls, and use any_external_decl to check
7474 against previous externals. Kill #if 0 blocks. Don't

7477 Objective C (the only user) needs.
