I guess you tried to build win32-api module with Visual C++ 9.0.
You must use the same compiler with the Ruby version(x64-mswin64_80).
After some trials and errors, I managed to build win32-api module with
Visual C++ 8.0.
You can download at http://121.78.227.9/win32-api-1.4.0/lib/win32/api.so

NB, Using win32utils on the 64bit Ruby is not tested.
