double constant used to initialise float member

[Rowan James <rowanj@…>]

In: multi_index/hashed_index.hpp: ~608

Class member 'mlf' is defined as a float, but the unqualified double constant 1.0 is used to initialise it.

This causes the following warning for us in code using boost::flyweights on GCC 4.2 (APPLE) with -Wall -Wextra

warning: implicit conversion shortens 64-bit value into a 32-bit value
