Problem with 2 class prototypes

[Jsel]

The problem is that I have 2 class prototypes that need to recognize one another before they can actually be written.

example..

class A
{
//member function prototypes here need
//to recognize class B.
};

class B
{
//member function prototypes here need
//to recognize class A.
};

So no matter what order they are written in, I will always get a compile error. Any solutions to this?

I tried putting each of the class prototypes in their own header file with the other one included using #include, but this won't work because the header files must be protected from multiple inclusion.. the pre-processor would run in an infinite loop otherwise i think. Thanks for any help.
