Support for specialising using a qualified name was only added in C++11. Unfortunately, GCC didn't catch up until GCC7. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56480 .

Revert to the C++03 method for the time being to support older GCC versions.

In particular, Debian 9 is still using GCC6 as its system compiler, so the tests don't compile there.

Thanks.

Not sure how could such a bug survive until GCC7, though...

Indeed.

Thanks for merging.
