Maybe it's better to leave the C++ definitions to libstdc++, where we
can use decltype and use arbitrarily complicated template
metaprogramming that probably isn't appropriate for glibc.

I think we want to fix the 2.26 release, so we need to do somethingwithout GCC's help here. The bug reports suggest to me that peoplereally want to use this functionality from C++.

I suppose we could restrict the definition to GNU compilers (which ave__typeof) or compilers which support C++11 (and thus decltype).


Thanks,
Florian
