First, I am using Dev-C++. When I try to compile any DirectX C++ source it gives me this error:

671 c:\dev-c_~1\include\objidl.h
`com_interface' only supported with -fvtable-thunks

I can't figure this out. I know I cross posted, but I made the subject too... deferrant. What does the -fvtable-thunks thing mean? Is it a compiler option? Thanks very much!
