6616 (pushlevel): Ignore argument. Do not push another binding
6617 level on the transition from the parameters to the top level
6618 of the function body; just tweak the flags and proceed.

6668 (poplevel): Delete #if 0 block. Make externals invisible
6669 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6670 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6671 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6672 (duplicate-decls): For real parm decl after a forward decl,
6673 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6677 local-over-local. Clarify comments.
