2045 we might have to diagnose "struct foo; union foo;"
2046 (pushlevel): Ignore argument. Do not push another binding
2047 level on the transition from the parameters to the top level
2048 of the function body; just tweak the flags and proceed.

2098 (poplevel): Delete #if 0 block. Make externals invisible
2099 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2100 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2101 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2102 (duplicate-decls): For real parm decl after a forward decl,
2103 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2107 local-over-local. Clarify comments.

2115 Objective C (the only user) needs.
2116 (pushdecl_function_level): New function.
2117 (implicitly_declare): Create ordinary decls with
