2010 we might have to diagnose "struct foo; union foo;"
2011 (pushlevel): Ignore argument. Do not push another binding
2012 level on the transition from the parameters to the top level
2013 of the function body; just tweak the flags and proceed.

2063 (poplevel): Delete #if 0 block. Make externals invisible
2064 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
2065 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2066 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2067 (duplicate-decls): For real parm decl after a forward decl,
2068 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

2072 local-over-local. Clarify comments.
