2085 (pushlevel): Ignore argument. Do not push another binding
2086 level on the transition from the parameters to the top level
2087 of the function body; just tweak the flags and proceed.

2137 (poplevel): Delete #if 0 block. Make externals invisible
2138 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2139 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2140 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2141 (duplicate-decls): For real parm decl after a forward decl,
2142 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2146 local-over-local. Clarify comments.

2154 Objective C (the only user) needs.
