Recently, I tried to use a protected base class, like this:

class A {
   ...
};

class B:protected A {
   ...
};

To my surprise, my compiler (based on CFront 2.0) refused to compile this.
The ARM doesn't seem to be clear about this: The syntax seems to allow it,
but the text and examples don't mention it.

My question is: If protected base classes are indeed illegal, why are they
and what speaks against adding them to C++ ?

I hope this question is not inappropriate for this newsgroup.
