C4430 emitted twice for the same construct by Dmitry Me

This behavior is observed in cl.exe 16.00.40219.1

I have this code (taken from http://msdn.microsoft.com/en-us/library/ms173696.aspx):

struct CMyClass {
CUndeclared m_myClass; // line 48
};

which I compile with /W4 and get this output:

1><path>\test.cpp(48): error C2146: syntax error : missing ';' before identifier 'm_myClass'
1><path>\test.cpp(48): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1><path>\test.cpp(48): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

Here C4430 is emitted twice for the same construct.
