Inialization and user-defined conversion

Hello c++ gurus,

I have a confusion with initialization of class objects.
Example:

class C {
 public:
	C(int i);
};

class D {
 public:
	D(C c);
};

D d = 1;

void f()
{
	D d = 1;
}

I assume, that both initializations are wrong, since they require sequence
of two user-defined conversions. But some compilers disaggre ;-)

Boralnd c++ 4.0:	cannot convert "int" to "D"
g++ 2.7.2:		no matching funcion for call to "D::D(int)"
MS VC 4.0:		no errors
Watcom 10.0:		no errors

As seems to me only Borland gives adequate diagnostics.

Who is right ? 

Thank you in advance,
