This fixes
FAIL: 22_locale/ctype/is/string/89728_neg.cc -std=gnu++98 (test for errors, line )
Since
r16-133-g8acea9ffa82ed8 we don't keep issuing more errors after
the first one, so this dg-error no longer matches anything.
libstdc++-v3/ChangeLog:
* testsuite/22_locale/ctype/is/string/89728_neg.cc: Remove
dg-error for c++98_only effective target.
// <http://www.gnu.org/licenses/>.
// { dg-error "invalid use of incomplete type" "" { target *-*-* } 0 }
-// { dg-error "invalid 'static_cast'" "" { target c++98_only } 0 }
