Subject: libstdc++: Remove unused local type alias <format>.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ec331001eaa1e42c6ff9536fa51aeaf2a1c86a6a;p=thirdparty%2Fgcc.git

libstdc++: Remove unused local type alias <format>.

After r16-4421-g59cabe08b57a26 the local type alias _String isn't used
anymore and therefore causes warnings when building the tests with
`-Wall -Wextra`.

libstdc++-v3/ChangeLog:

	* include/std/format (_M_format_range): Remove unused local type
	alias _String.
