I have filed:
	-fdebug-types-section regresses ststic scope of types
	http://sourceware.org/bugzilla/show_bug.cgi?id=14148

As I do not intend to fix it proposing KFAIL below.  The fix needs to start
tracking types signatures during psymtab building to look up the type name
during psymtab-scanning DW_TAG_variable.


Thanks,
Jan

	Setup KFAIL symtab/14148.
	* py-symbol.c (static_func): New static function.
	(main): New variable result1, call static_func.
	* py-symtab.exp (Test static_func in static symbols): New test.
	(Test simple_struct in static symbols): KFAIL it with .debug_types.
