8833 level on the transition from the parameters to the top level
8834 of the function body; just tweak the flags and proceed.

8884 (poplevel): Delete #if 0 block. Make externals invisible
8885 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8886 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8887 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8888 (duplicate-decls): For real parm decl after a forward decl,
8889 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8893 local-over-local. Clarify comments.
