/* We have to have CDummySubConnectionProvider inside the ESock namespace so it can befriend
mcfnode_cast - GCC simply doesn't allow befriending something in another template. See
http://gcc.gnu.org/ml/gcc-prs/2002-10/msg01010.html for Herb Sutter's GOTW column on exactly
this - it contains this discouraging summary:

The reason that I'm writing an article about it is because, alas,
befriending a template in another namespace is easier said than done:

- The Bad News: There are two perfectly good standards-conforming
 ways to do it, and neither one works on all current compilers.

- The Good News: One of the perfectly good standards-conforming ways
 does work on every current compiler I tried except for gcc.

So, since it's only test code & we need it building on GCC, I've hacked around it */
