In fact, both symbols are used, but not defined:
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC1EP6__FILESt13_Ios_Openmodej
=
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEEC2EP6__FILESt13_Ios_Openmodej
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC1EP6__FILESt13_Ios_Openmodej
=
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEEC2EP6__FILESt13_Ios_Openmodej
gas can cope with that, Sun as cannot. I'll have to start a reghunt for the
culprit patch.
