Yes, that makes sense. I do link to -lwthttp (as well as -lwt). This
resolves to libwthttp.a, a mingw-w64 / windows static library that
presumably has boost::asio linked into it.

Thank you. Your linux experience makes perfect sense to me. The
mystery is why my windows version doesn't work the way I would
expect conventional socket code to work, even on windows.
It doesn't seem likely that something like this would have changed
between 3.3.3 and 3.3.4. It's probably just some windows weirdness.
This isn't really an issue for me -- I was just surprised when I noticed
this behavior.
Best regards.
