2035 we might have to diagnose "struct foo; union foo;"
2036 (pushlevel): Ignore argument. Do not push another binding
2037 level on the transition from the parameters to the top level
2038 of the function body; just tweak the flags and proceed.

2088 (poplevel): Delete #if 0 block. Make externals invisible
2089 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2090 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2091 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2092 (duplicate-decls): For real parm decl after a forward decl,
2093 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2097 local-over-local. Clarify comments.

2105 Objective C (the only user) needs.
2106 (pushdecl_function_level): New function.
2107 (implicitly_declare): Create ordinary decls with
