thanks for the contribution, I've just added it in the trunk code base.
I've pruned redundant inclusions, move inclusion to cpp file when
possible, expanded error messages to be more informative, and avoided
instantiating objects in the GaussianCopula::operator() method since
they could be instantiated once for all in the constructor.
It would be nice if you would contribute a unit test which reproduces
known tabulated values. This way I could have checked that I didn't
introduce any error ;-)
One question: you contributed bidimensional copulas. Is there an
efficient standard approach how to generalize to arbitrary dimensions?

using the quantlib-dev mailing list would have been better, but I am
aware that the line between users and developers is blurred when it
comes to a C++ library.
You might want to reply only to the quantlib-dev address for further
discussions in this thread.
Thank you again
