Excellent.

It might be useful to document the actual warning number for those Googling
Boost documentation for a solution their problem.

For MSVC 7.1, writing x = 0; and not using it produces

warning C4189: 'x' : local variable is initialized but not referenced.

And that this is level 4 warning, not shown on the default level 3 setting :-(

This should encourage people to up their warning level who before might have
been discouraged by the spurious warnings.

(Similarly for other compilers of course).

And reassure that there should be no run-time cost?
