8896 (poplevel): Delete #if 0 block. Make externals invisible
8897 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't

8899 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8900 (duplicate-decls): For real parm decl after a forward decl,
8901 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8905 local-over-local. Clarify comments.
