9209 (pushlevel): Ignore argument. Do not push another binding
9210 level on the transition from the parameters to the top level
9211 of the function body; just tweak the flags and proceed.

9261 (poplevel): Delete #if 0 block. Make externals invisible
9262 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9263 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9264 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9265 (duplicate-decls): For real parm decl after a forward decl,
9266 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9267 foo(...) { } with only a warning. Say whether a previous
9268 declaration was implicit.

9270 local-over-local. Clarify comments.
9271 (pushdecl): Rewritten. There is no longer a distinction
9272 between global and local symbol values; they're all
9273 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9274 DECL_EXTERNAL decls, and use any_external_decl to check
9275 against previous externals. Kill #if 0 blocks. Don't
9276 tolerate error_mark_node being NULL.

9278 Objective C (the only user) needs.
9279 (pushdecl_function_level): New function.
9280 (implicitly_declare): Create ordinary decls with

9301 IDENTIFIER_GLOBAL_VALUE.
