Actually the problem is a missing define for WIN32. Newer
Platform SDKs (like the one I use) automatically #define WIN32
for you in WinDef.h, but the one shipped with VC7.1 does not. If
WIN32 is not defined, Winsock2.h assumes you are compiling for
16-bit Windows (!) and redefines the WSAOVERLAPPED structure
instead of just making it a typedef for OVERLAPPED.
You can work around the problem by adding the WIN32 definition
to your makefile/Jamfile/project settings. I have made a change
to asio/detail/socket_types.hpp in asio's CVS repository to
automatically define it, and will merge the change over to Boost
CVS soon.
Cheers,
Chris
