Hi,

I recently tried to compile some C++11 program that does not use any
deprecated feature from C++03 with option -D_GLIBCXX_USE_DEPRECATED=0.
I thought it would improve the compile time.
However, it does not compile since the function std::bind2nd is still used into the file <bits/random.tcc>.

Should the library be changed so that valid C++11 code does not have to rely on deprecated features anymore?

Bah. In the *specific* case at issue, I suppose we can as well do away with the binding dance, because we always have the same __transform and the same std::divides functor. Probably it made sense when the initiali <random> code went in. For 4.8 I'm finishing testing the below.

Thanks,
Paolo.
