2016 we might have to diagnose "struct foo; union foo;"
2017 (pushlevel): Ignore argument. Do not push another binding
2018 level on the transition from the parameters to the top level
2019 of the function body; just tweak the flags and proceed.

2069 (poplevel): Delete #if 0 block. Make externals invisible
2070 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2071 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2072 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2073 (duplicate-decls): For real parm decl after a forward decl,
2074 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2078 local-over-local. Clarify comments.
