---------------- 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
It appears to me that you can only get this error if you have defined WINVER to be something less than 0x0500, which means the software you are building is attempting to support a version of windows PRIOR to Windows 2000. Is this your intention? Try defining WINVER to be 0x0500 (if you want to run on Win2k and higher) and 0x0501 (if you want to run on WinXP+)

This could be related to the first issue. DWORD* and PULONG_PTR are supposed to be exactly the same type when compiling for x64 on recent operating systems. So it makes me think that the compiler thinks you're on a really old operating system. I would try this #define WINVER 0x0501 #define _WIN32_WINNT 0x0501 either in your stdafx.h if you use precompiled header, or as a command line option if you don't.
