Hi,

Attached is an updated patch correcting the issues that you pointed
out.

Cheers,

Phil

	http://sourceware.org/bugzilla/show_bug.cgi?id=15195

	* python/libstdcxx/v6/printers.py (StdTuplePrinter.__init__):
	Acquire referenced value if tuple is a reference.
	* testsuite/libstdc++-prettyprinters/cxx11.cc (main): Add -O0
	flag. Add tuple and referenced tuple tests.
