Somehow I messed up the test in the commit I pushed (but not the one I
tested ... weird).

Fixed at r13-1151-g0f96ac43fa0a5f by the attached patch.

   libstdc++: Add missing #include <string> to new test

   Somehow I pushed a different version of this test to the one I actually
   tested.

   libstdc++-v3/ChangeLog:

           * testsuite/21_strings/basic_string/cons/char/105995.cc: Add
           missing #include.
