Warning c4273: inconsistent DLL links

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 des this. h file will
Not have the macro defined and will use the dllimport directive.
