[cfe-dev] std::tr1::variate_generator

Thank you all for your helpful replies.  
I am using boost/tr1/random.hpp from 1.49.0 to fix the library code I am working with.
I will report the wider issues to the author of the library, who had not I think compiled it with clang.
As usual it is easy to learn new things in this community.

libc++ implements C++11, not TR1.  variate_generator
didn't make it into the standard.
