Compiler Warning (level 3) C4192

automatically excluding 'name' while importing type library 'library'

While doing a #import of library, an item, name, was encountered that is also defined in the Win32 system headers.  Due to limitations of type libraries, names such as IUnknown or GUID will often be defined in a type library, duplicating the definition from the system headers.  #import will detect these items and refuse to incorporate them in the .TLH and .TLI header files.

#import attributes no_auto_exclude and include(...) can be used to override this behavior.
