Mark function declarations as CPPU_DLLPUBLIC, not only definitions

<http://msdn.microsoft.com/en-us/library/8fskxacy.aspx> "Importing into an
Application Using __declspec(dllimport)":  "Using __declspec(dllimport) is
optional on function declarations, but the compiler produces more efficient code
if you use this keyword."
