Subject: Remove unused std::_Iter_base class template
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=94ed6c0aaf7f16112bd50296d96e6bfac4949bdd;p=thirdparty%2Fgcc.git

Remove unused std::_Iter_base class template

This class template has been unused since __gnu_debug::__base was
removed in r263786.

	* include/bits/stl_iterator_base_types.h (_Iter_base): Remove unused
	class template and partial specialization.
