	std::index_sequence and std::index_sequence_for are new in C++14,
	but this version of glibmm requires only C++11.
	The code that replaces std::index_sequence has been provided by
	Jonathan Wakely <zilla@kayari.org>. Bug 787648

	Gio::Application docs: Add a note to property_resource_base_path()

	Fixing this would break API and ABI. A fix has to wait until the next
	API/ABI break. For now, add a note to the documentation. Bug 787496
