Subject: libstdc++: Fix mingw build by using _M_span [PR119970]
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1be88e43f3e93e85bef9499de905fa72d8596e7d;p=thirdparty%2Fgcc.git

libstdc++: Fix mingw build by using _M_span [PR119970]

The r16-142-g01e5ef3e8b9128 chagned return type of _Str_sink::view()
to basic_string_view<_CharT>. The mutable access is provided by _M_span
function, that is now used for mingw path.

	PR libstdc++/119970

libstdc++-v3/ChangeLog:

	* include/std/ostream (vprint_unicode) [_WIN32 && !__CYGWIN__]: Call
	_Str_sink::_M_span instead of view.
	* include/std/print (vprint_unicode) [_WIN32 && !__CYGWIN__]: Call
	_Str_sink::_M_span instead of view.
