2061 (pushlevel): Ignore argument. Do not push another binding
2062 level on the transition from the parameters to the top level
2063 of the function body; just tweak the flags and proceed.

2113 (poplevel): Delete #if 0 block. Make externals invisible
2114 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2115 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2116 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2117 (duplicate-decls): For real parm decl after a forward decl,
2118 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2122 local-over-local. Clarify comments.

2130 Objective C (the only user) needs.
