Compiler Error C2287

'class': inheritance representation: 'representation1' is less general than the required 'representation2'

A class is declared with a simpler representation than required.

The following sample generates C2287:

// C2287.cpp
// compile with: /vmg /c
class __single_inheritance X;
class __single_inheritance Y;

struct A { };
struct B { };
struct X : A, B { };  // C2287  X uses multiple inheritance
struct Y : A { };  // OK
