2949 (pushlevel): Ignore argument. Do not push another binding
2950 level on the transition from the parameters to the top level
2951 of the function body; just tweak the flags and proceed.

3001 (poplevel): Delete #if 0 block. Make externals invisible
3002 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3003 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3004 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3005 (duplicate-decls): For real parm decl after a forward decl,
3006 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

3010 local-over-local. Clarify comments.
