5727 (pushlevel): Ignore argument. Do not push another binding
5728 level on the transition from the parameters to the top level
5729 of the function body; just tweak the flags and proceed.

5779 (poplevel): Delete #if 0 block. Make externals invisible
5780 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5781 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5782 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5783 (duplicate-decls): For real parm decl after a forward decl,
5784 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

5788 local-over-local. Clarify comments.
