libstdc++: Add C++11 member functions for ios::failure in old ABI
The new constructors that C++11 added to std::ios_base::failure were missing for the old ABI. This adds them, but just ignores the std::error_code argument (because there's nowhere to store it). This also adds a code() member, which should be provided by the std::system_error base class, but that base class isn't present in the old ABI. This allows the old ios::failure to be used in code that expects the new API, although with reduced functionality. libstdc++-v3/ChangeLog: * include/bits/ios_base.h (ios_base::failure): Add constructors takeing error_code argument. Add code() member function. * testsuite/27_io/ios_base/failure/cxx11.cc: Allow test to run for the old ABI but do not check for derivation from std::system_error. * testsuite/27_io/ios_base/failure/error_code.cc: New test.
