Subject: libstdc++: Use new <bits/monostate.h> header in <format>
X-Git-Tag: basepoints/gcc-16~1546
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8a3944b440777d2d6fb4a9f456189a0dc439ec8;p=thirdparty%2Fgcc.git

libstdc++: Use new <bits/monostate.h> header in <format>

In r15-5832-g91f4550e1700b7 std::monostate was moved to its own header,
which means that <format> no longer needs to include all of <variant>.

libstdc++-v3/ChangeLog:

	* include/std/format: Include <bits/monostate.h> instead of
	<variant>.
