warning C4273: dll 連結不一致

 warning C4273: '<somefunction>' : inconsistent dll linkage

I have other DLLs that have been created using the same basic pattern. I
using the approach where the following code appears in the .h file:

#ifdef HYCOMMONWINAPI_EXPORTS
#define HYCOMMONWINAPI_API__declspec(dllexport)
#else
#define HYCOMMONWINAPI_API __declspec(dllimport)
#endif

Each of the functions in the .h file are prefixed with this macro:

HYCOMMONWINAPI_API unsigned int myfunc();

The DLL project defines the MYDLL_EXPORTS symbol so that the specified
functions are exported. Conversely, any app that includes this .h file will
not have the macro defined and will use the dllimport directive.
