To fix this warning, either correct the declaration or delete the declaration and simply #include the appropriate header file.
The following sample generates C4391:
// C4391.cpp
// compile with: /W1
// processor: x86
// uncomment the following line and delete the line that
// generated the warning to resolve
// #include "xmmintrin.h"
#ifdef __cplusplus
extern "C" {
#endif
extern void _mm_load_ss(float *p); // C4391
#ifdef __cplusplus
}
#endif
int main()
{
}
