[C++-sig] boost::python and gcc 3.4

[Nick Rasmussen]

Now that gcc 3.4 is enforcing the standard more strictly, what's
the new way of doing:

     handle<> main_module(borrowed( PyImport_AddModule("__main__") ));

(taken from the embedding section of the tutorial)

Without triggering a copy constructor call on a boost::noncopyable
object.

Here's the relevant traffic from the gcc guys as to why the copy
constructor's getting called:
