'identifier' : definition of dllimport function not allowed

Data, static data members, and functions can be declared as dllimports but not defined as dllimports.

To fix this issue, remove the __declspec(dllimport) specifier from the definition of the function.

The following sample generates C2491:

// C2491.cpp
// compile with: /c
// function definition
void __declspec(dllimport) funcB() {}   // C2491

// function declaration
void __declspec(dllimport) funcB();   // OK
