I am having a problem compiling a program in Visual Studio 2010, on a windows 7 computer. I get the below errors when I compile in Release mode, but not in Debug mode. I have carefully checked all the property settings for both modes, and they are the same, except for where they have to be different; the code generation setting is /MD for Runtime, and /MDd for Debug, the same settings that I compiled the wxWidgets (2.8.12) libraries under, and the names of the wxWidgets libraries are slightly different. As I say, I have no problem compiling and running my program in Debug mode, or running wxWidgets samples in either mode. I also am linking to wxMathPlot, which is a wxWidgets add-on, I don't know if that is relevant. I can run the debug or release versions of wxMathPlot samples.
Now Microsoft has a little bit of information on these compiler errors, but nothing that helped me too much:

This statement seems relevant: "You may also get C2011 if you import a type library more than once into the same file"
Except that I don't know what that means, or how I might be doing it. It seems curious that I would be doing it for one mode and not the other. Has anyone seen this problem and know how to overcome it?
Thanks Phil

Here is a piece of code that it is complaining about from the unknwn.h file, starting on line 124:
template<class Q>
HRESULT
#ifdef _M_CEE_PURE
__clrcall
#else
STDMETHODCALLTYPE
#endif
QueryInterface(Q** pp)
