As a practical matter, if your code has 100 false warnings, there's no chance
you'll notice 101-th warning that's result of real bug. Therefore, you either
eliminate all warnings, enable -Werror and investigate all new warnings that
occur, or you don't use warnings at all. I prefer -Werror, and therefore if
Boost headers produce zillion of warnings, that's rather bad.

Now, it might be impractical to expect anybody to spend day workarounding
an obscure warning on a compiler nobody uses, but all warning patches I saw
posted are rather simple, so maybe there's no hard-to-workaround warnings
at all.
