1394 we might have to diagnose "struct foo; union foo;"
1395 (pushlevel): Ignore argument. Do not push another binding
1396 level on the transition from the parameters to the top level
1397 of the function body; just tweak the flags and proceed.
1398 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1399 a function body, separate the parameter list from the
1400 top-level local variables.
1401 (set_block): Do nothing.
1402 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
1403 shadowed_tags if necessary.

1450 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1451 (duplicate-decls): For real parm decl after a forward decl,
1452 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1460 DECL_EXTERNAL decls, and use any_external_decl to check
1461 against previous externals. Kill #if 0 blocks. Don't
1462 tolerate error_mark_node being NULL.

1464 Objective C (the only user) needs.
