#8779: normal_distribution<float> warnings about narrowing conversions

Milestone:  To Be Determined         |  Component:  random

-------------------------------------+-----------------------------
 msvc-11 and other compilers complain about the following in
 normal_distribution.hpp when `normal_distribution<>` is instantiated with
 `float`:

 {{{
     template<class Engine>
     RealType generate_tail(Engine& eng) {
         boost::random::exponential_distribution<RealType> exponential;
         const RealType tail_start(normal_table<double>::table_x[1]);
 }}}

 The last line is, indeed, a narrowing conversion. Would be great if you
 could add a cast to silence this noisy warning.
