3541 (pushlevel): Ignore argument. Do not push another binding
3542 level on the transition from the parameters to the top level
3543 of the function body; just tweak the flags and proceed.

3593 (poplevel): Delete #if 0 block. Make externals invisible
3594 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3595 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3596 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3597 (duplicate-decls): For real parm decl after a forward decl,
3598 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

3602 local-over-local. Clarify comments.
3603 (pushdecl): Rewritten. There is no longer a distinction
3604 between global and local symbol values; they're all
3605 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
3606 DECL_EXTERNAL decls, and use any_external_decl to check
3607 against previous externals. Kill #if 0 blocks. Don't
3608 tolerate error_mark_node being NULL.

3610 Objective C (the only user) needs.
3611 (pushdecl_function_level): New function.
3612 (implicitly_declare): Create ordinary decls with

3625 global_binding_level in extremis.
