It doesn't prevent LO from building but thought it could be interesting to
pinpoint.
Yeah, that's a general issue since
<https://git.libreoffice.org/core/+/e0f1b5bd94550835c639efda4e4c9a801c78dbe9%5E!/>
"Upgrade external/boost to latest Boost 1.75.0". But as it doesn't
affect --enable-werror, I didn't deem it worthwhile to silence the noise
by ignoring -W#pragma-messages in bin/gen-boost-headers (and whatever
would be necessary for MSVC). If we hate the noise enough, though, we
could presumably patch external/boost's json_parser according to the
pragma message ("use <boost/bind/bind.hpp> + using namespace
boost::placeholders").
