5731 (pushlevel): Ignore argument. Do not push another binding
5732 level on the transition from the parameters to the top level
5733 of the function body; just tweak the flags and proceed.

5783 (poplevel): Delete #if 0 block. Make externals invisible
5784 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5785 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5786 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5787 (duplicate-decls): For real parm decl after a forward decl,
5788 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

5792 local-over-local. Clarify comments.
