1770 (pushlevel): Ignore argument. Do not push another binding
1771 level on the transition from the parameters to the top level
1772 of the function body; just tweak the flags and proceed.

1822 (poplevel): Delete #if 0 block. Make externals invisible
1823 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1824 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1825 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1826 (duplicate-decls): For real parm decl after a forward decl,
1827 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1831 local-over-local. Clarify comments.
1832 (pushdecl): Rewritten. There is no longer a distinction
1833 between global and local symbol values; they're all
1834 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1835 DECL_EXTERNAL decls, and use any_external_decl to check
1836 against previous externals. Kill #if 0 blocks. Don't
1837 tolerate error_mark_node being NULL.

1839 Objective C (the only user) needs.
1840 (pushdecl_function_level): New function.
1841 (implicitly_declare): Create ordinary decls with

1854 global_binding_level in extremis.
