7462 level on the transition from the parameters to the top level
7463 of the function body; just tweak the flags and proceed.

7513 (poplevel): Delete #if 0 block. Make externals invisible
7514 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7515 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7516 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7517 (duplicate-decls): For real parm decl after a forward decl,
7518 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

7522 local-over-local. Clarify comments.
