2969 (pushlevel): Ignore argument. Do not push another binding
2970 level on the transition from the parameters to the top level
2971 of the function body; just tweak the flags and proceed.

3021 (poplevel): Delete #if 0 block. Make externals invisible
3022 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3023 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3024 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3025 (duplicate-decls): For real parm decl after a forward decl,
3026 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

3030 local-over-local. Clarify comments.
