2974 (pushlevel): Ignore argument. Do not push another binding
2975 level on the transition from the parameters to the top level
2976 of the function body; just tweak the flags and proceed.

3026 (poplevel): Delete #if 0 block. Make externals invisible
3027 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3028 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3029 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3030 (duplicate-decls): For real parm decl after a forward decl,
3031 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

3035 local-over-local. Clarify comments.

3043 Objective C (the only user) needs.
