1549 we might have to diagnose "struct foo; union foo;"
1550 (pushlevel): Ignore argument. Do not push another binding
1551 level on the transition from the parameters to the top level
1552 of the function body; just tweak the flags and proceed.

1602 (poplevel): Delete #if 0 block. Make externals invisible
1603 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1604 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1605 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1606 (duplicate-decls): For real parm decl after a forward decl,
1607 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1611 local-over-local. Clarify comments.

1619 Objective C (the only user) needs.
1620 (pushdecl_function_level): New function.
