[Bug libstdc++/36173] New: abi breakage, stdio_filebuf routines missing

[mrs at apple dot com]

A few routines seem to have disappeared from 4.0.0 to 4.2.1:

    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEE2fdEv;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEE4fileEv;
   
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC1EP7__sFILESt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC1EiSt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC1Ev;
   
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC2EP7__sFILESt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC2EiSt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC2Ev;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED0Ev;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED1Ev;
    _ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED2Ev;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEE2fdEv;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEE4fileEv;
   
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC1EP7__sFILESt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC1EiSt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC1Ev;
   
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC2EP7__sFILESt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC2EiSt13_Ios_Openmodem;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC2Ev;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED0Ev;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED1Ev;
    _ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED2Ev;
    _ZTVN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEE;
    _ZTVN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEE;

Adding these back to libstdc++-v3/config/abi/pre/gnu.ver seems to make it
better.
