No, the problem isn't in that typedef, which must be like that, per TR1. The
problem is a limitation of the tr1::uniform_int which doesn't work for an
UniformRandomNumberGenerator which generates numbers in a range smaller than
the required uniform_int output range (see the XXX comment). Fixing that was
not trivial, but it is now fixed in the C++0x uniform_int, whereas the TR1 code
ad this time is frozen, I'm sorry, if you still want to use it, please work
around the limitation (there are many ways).
