2024 we might have to diagnose "struct foo; union foo;"
2025 (pushlevel): Ignore argument. Do not push another binding
2026 level on the transition from the parameters to the top level
2027 of the function body; just tweak the flags and proceed.

2077 (poplevel): Delete #if 0 block. Make externals invisible
2078 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2079 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2080 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2081 (duplicate-decls): For real parm decl after a forward decl,
2082 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2086 local-over-local. Clarify comments.
