Right you are Brian! 

Thanks, now the dll works as expected from Visual Studio. 

The DLL menace was at an end. The quest for the Holy Grail could
continue...

Here's what works for me:

testdll.h:

#ifdef __cplusplus
extern "C" {
#endif

__declspec(dllimport) int call_me(int i);

#ifdef __cplusplus
}
#endif




testdll.c:

__declspec(dllexport) int
call_me(int i)
{
   return i-5;
}

Thanks Brian!
