Subject: [PATCH] Remove unnecessary typedef from std::function
Authentication-results: sourceware.org; auth=none

TThis typedef is only used once, in a function body, so it doesn't
need to be defined at class scope. It doesn't need to be defined at
all.

	* include/bits/std_function.h (function::_Signature_type): Remove.
	(function::function(_Functor)): Adjust.

Tested powerpc64le-linux, committed to trunk.
