Code with exception specifications that are ignored during compilation may need to be recompiled and linked to be reused in future versions supporting exception specifications.
For more information, see Exception Specifications .
You can avoid this warning by using the warning pragma:
#pragma warning( disable : 4290 )

// C4290.cpp
// compile with: /EHs /W3 /c
void f1(void) throw(int) {} // C4290
// OK
void f2(void) throw() {}
void f3(void) throw(...) {}
