[boost] Bug in random/uniform_real.hpp

Dear Boosters, dear Jens,

After some debugging I realized another bug in the new version of the 
Boost random number library. uniform_real has the following operator():

   result_type operator()(Engine& eng) { return eng() * (_max - _min) + 
_min; }

This does not work if the underlying engine does not give random 
numbers in an interval other than [0,1), and thus fails with all of the 
integer based engines in the Boost random library. Is it necessary to 
wrap the engine in a uniform_01 object? But then it would fail for the 
uniform_integer distributions? Either I am missing something here or 
the Boost random library is in an inconsistent and broken state. Could 
Jens or somebody else help me?
