[Bug c++/24511] [4.0/4.1 Regression] explicit instantiation/extern template unsats on symbols defined later

I do disagree with your reasoning on the other bug.  This DR clarifies 14.7.2:

  http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#470

If indeed all other compilers accept this code, then perhaps the DR is not what
we want, but you should bring that up with Core.

Jason, I respectfully disagree. In bug 22263 I explained why I believe gcc is
wrong. Do you see a problem with my reasoning there? If not, you must surely
agree that this is just another example of the same bug.

This is not a bug.  All member templates must be defined before an explicit
instantiation of the class.  The existing standard requires an error on this
case, but a future DR will change the standard to match the g++ behavior.

It's desirable to not require all member templates to be defined in the case of
private copy constructors declared only to prevent copying the class.
