Hi!
We've been using Boost 1.38.0:
        WinXP SP3  on  32-bit box
        VisualStudio 2005, MSVC++ 8.0, 32-bit builds.

I've just rebuilt Boost 1.38.0 on another system for 64-bit builds:
        Windows Server 2008 Enterprise SP1
        VisualStudio 2008, MSVC++ 9.0, 64-bit builds.

Found no visible build errors during the Boost build.

Yet when I build our own code on the 64-bit system, I get these three compile errors deep inside boost::asio code that I have no control over:

>>----------------
error C2664: 'QueueUserAPC' : cannot convert parameter 1 from 'void (__cdecl *)(ULONG)' to 'PAPCFUNC'   D:\dev\3rdParty_x64\include\boost\asio\detail\win_thread.hpp    151

>>----------------
error C2664: 'GetQueuedCompletionStatus' : cannot convert parameter 3 from 'DWORD *' to 'PULONG_PTR'    D:\dev\3rdParty_x64\include\boost\asio\detail\win_iocp_io_service.hpp   142

>>----------------
error C2664: 'GetQueuedCompletionStatus' : cannot convert parameter 3 from 'DWORD *' to 'PULONG_PTR'    D:\dev\3rdParty_x64\include\boost\asio\detail\win_iocp_io_service.hpp   430

>>----------------

The "D:\dev\3rdParty_x64" is where I've installed the includes & libs for Boost and other components.

As you can see, those errors are not in our code; they're deep in the ASIO code itself, and I don't see how we could be causing them.  I didn't write our code that uses ASIO, so I don't know anything about what ASIO is trying to do there.  :(

Since I couldn't find any other complaints online about this, I'm flailing around for support.

Any pointers would be appreciated.

Pertinent data:
        64-bit WindowsServer2008 SP1 on Intel 64-bit box
        VisualStudio2008 SP1   (SP2 is still RC, I think, so we can't use it.)
        Our projects using "x64" configuration, so uses x64 compiler.
        Boost built with x64 compiler via:  toolset=msvc-9.0  address-model=64

        Thanks!
