The proper test program now looks like this:

   boost::lagged_fibonacci607 rng;
   boost::uniform_int<> int_rng(0,3);
   boost::variate_generator<boost::lagged_fibonacci607&, boost::uniform_int<> > uni(rng, int_rng);
   int x = uni();

See libs/random/random_demo.cpp

Please tell me where the documentation still refers to the old format.

Using boost::lagged_fibonacci607& in the variate_generator<> indicates that
we pass rng by reference, and it's your job to care for the lifetimes.
boost::lagged_fibonacci607* works as well, and the syntax is expandable
to smart pointers if the rng you pass in is a smart_ptr with automatic
lifetime management.
