6583 (pushlevel): Ignore argument. Do not push another binding
6584 level on the transition from the parameters to the top level
6585 of the function body; just tweak the flags and proceed.

6635 (poplevel): Delete #if 0 block. Make externals invisible
6636 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6637 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6638 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6639 (duplicate-decls): For real parm decl after a forward decl,
6640 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6644 local-over-local. Clarify comments.
