1966 we might have to diagnose "struct foo; union foo;"
1967 (pushlevel): Ignore argument. Do not push another binding
1968 level on the transition from the parameters to the top level
1969 of the function body; just tweak the flags and proceed.

2019 (poplevel): Delete #if 0 block. Make externals invisible
2020 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2021 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2022 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2023 (duplicate-decls): For real parm decl after a forward decl,
2024 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2028 local-over-local. Clarify comments.
