1281 (pushlevel): Ignore argument. Do not push another binding
1282 level on the transition from the parameters to the top level
1283 of the function body; just tweak the flags and proceed.

1333 (poplevel): Delete #if 0 block. Make externals invisible
1334 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1335 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1336 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1337 (duplicate-decls): For real parm decl after a forward decl,
1338 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1342 local-over-local. Clarify comments.
1343 (pushdecl): Rewritten. There is no longer a distinction
1344 between global and local symbol values; they're all
1345 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1346 DECL_EXTERNAL decls, and use any_external_decl to check
1347 against previous externals. Kill #if 0 blocks. Don't
1348 tolerate error_mark_node being NULL.

1350 Objective C (the only user) needs.
1351 (pushdecl_function_level): New function.
1352 (implicitly_declare): Create ordinary decls with
