1961 we might have to diagnose "struct foo; union foo;"
1962 (pushlevel): Ignore argument. Do not push another binding
1963 level on the transition from the parameters to the top level
1964 of the function body; just tweak the flags and proceed.

2014 (poplevel): Delete #if 0 block. Make externals invisible
2015 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2016 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2017 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2018 (duplicate-decls): For real parm decl after a forward decl,
2019 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2023 local-over-local. Clarify comments.
