I've got two classes, ObjClass1 and ObjClass2. I need them to both
know about one another but I can't include the header twice because of
a "type redefinition" even though it's the same file. Ex:

-----ObjClass1.h-----

#ifndef __OBJCLASS1
#define __OBJCLASS1

#include "ObjClass2.h"

public ref class ObjClass1
{
// Stuff
ObjClass2 ^obj2;
};

#endif


-----ObjClass2.h-----

#ifndef __OBJCLASS2
#define __OBJCLASS2

#include "ObjClass1.h"

public ref class ObjClass2
{
// Stuff
ObjClass1 ^obj1;
};

#endif

Now, with this configuration the compiler just complains that there's
no type ObjClass1 and ObjClass2 for the opposite's header file. So I
tried to undef __OBJCLASS1 in ObjClass2.h to try to fix that problem,
but then it says that I'm redefining ObjClass1 since ObjClass1's
header includes ObjClass2.h which includes ObjClass1 again.

At this point I figured I would just put a forward declaration in each
header:

ref class ObjClass1;

ref class ObjClass2;

But when I do this and try to call a function in the object, the
compiler complains that it has no clue what ObjClass1 and ObjClass2
are.

I'm getting really frustrated by this. Is there any way to fix it?
