1544 we might have to diagnose "struct foo; union foo;"
1545 (pushlevel): Ignore argument. Do not push another binding
1546 level on the transition from the parameters to the top level
1547 of the function body; just tweak the flags and proceed.

1597 (poplevel): Delete #if 0 block. Make externals invisible
1598 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1599 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1600 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1601 (duplicate-decls): For real parm decl after a forward decl,
1602 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1603 foo(...) { } with only a warning. Say whether a previous
1604 declaration was implicit.

1606 local-over-local. Clarify comments.

1614 Objective C (the only user) needs.
1615 (pushdecl_function_level): New function.
1616 (implicitly_declare): Create ordinary decls with
