6126 (pushlevel): Ignore argument. Do not push another binding
6127 level on the transition from the parameters to the top level
6128 of the function body; just tweak the flags and proceed.

6178 (poplevel): Delete #if 0 block. Make externals invisible
6179 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6180 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6181 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6182 (duplicate-decls): For real parm decl after a forward decl,
6183 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

6187 local-over-local. Clarify comments.
6188 (pushdecl): Rewritten. There is no longer a distinction
6189 between global and local symbol values; they're all
6190 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6191 DECL_EXTERNAL decls, and use any_external_decl to check

6195 Objective C (the only user) needs.
