            Bug ID: 64857
           Summary: Headers missing from <bits/stdc++.h> and
                    <bits/extc++.h>
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org

In C++11 mode <bits/extc++.h> doesn't include any of the standard headers:

 #if __cplusplus < 201103L
 #include <bits/stdtr1c++.h>
 #endif

and <bits/stdc++.h> doesn't include <codecvt> or <shared_mutex>.

I'll fix this in stage 1.
