Kenton, I solved the issue. The problem is that in your source code there are references to functions read, write and close which are the old POSIX versions. Microsoft has deprecated these functions in favor of the ISO compliant ones namely _read _write and _close. See http://msdn.microsoft.com/en-us/library/ms235412(VS.80).aspx I had to change the function calls in zero_copy_stream_impl.cc to use the newer '_' versions and then the linker errors went away while building my application. I didnt find any other places where the older references were being used.
I think you need to update your source to handle this issue.
