Are you using precompiled headers?

I haven't tested with MSVC8 yet, I'll give it a whirl through MSVC 2008
Express Edition (MSVC9 I think) soon.

Thanks for the report.

I think there's a macro that needs to be defined to tell Asio to not
include the windows headers. I forget exactly what that macro is, but it
should be documented in Asio.

Hmmm... I had encountered this problem with GCC, but it seemed to get
fixed along with the changes I made. Although I haven't tried including
just <boost/network/protocol/http.hpp>, I'll see what I can do there.
I'll try to reproduce.

That's odd... It fails when compiling message_test.cpp too.

Thanks for the report, I'll try to reproduce.
