Consider:
template <typename> void f() {}
extern template void f<int>();
When compiled with:
g++ -pedantic -std=c++0x -c t.cpp
the following warning is emitted:
warning: ISO C++ forbids the use of extern on explicit instantiations
Since extern template has already been integrated into the C++0x working paper,
I think this warning should not be emitted when using -std=c++0x, not even with
-pedantic.
