Not at all.  It's a continuing problem, but I think the 'solution' is to suppress warnings in a way that *documents* saying:

"Yes, we know, you would get a warning from this, but someone who ought to know (author etc) has decided that it isn't a helpful
warning - so you won't".

Sadly, there isn't a portable way of doing this (something Standards people should be apologising for), so for Boost it's a load of
hassle.

But it's most off-putting to get a zillion lines of warnings when you compile a simple bit of Boost - you certainly don't get a
chance to find warnings that apply to your own code, never mind the errors.

So I think we should continue to put effort into reducing the risk that Boost code  causes spurious warnings.
