The line you are wanting is
#define C const
You may assume that box, xform_split, and parallelogram are classes, that insidebox() is a member function of class parallelogram, and that inverse_image() and intersect() are functions.
With those additions, it becomes quite reasonable C++ code. In fact, I've now made it compile and execute, but that's not the point.
The point is not whether the code was correct, the point is that the error message was not useful. I don't want to point out the obvious, but the entire function of a C++ compiler is to help people write computer programs, and since people make mistakes (or at least I do), part of a compiler's job is to help the programmer correct his or her errors. Providing helpful error messages is a good way to do this.
The functioning code is as follows:
#define C const
box c_area(C xform_split &xf, C box& databox0, C box& databox1)
{
C parallelogram inv_image_db0(inverse(xf.back), databox0);
C box box0inOUTin(inv_image_db0.insidebox());
C box lc(inverse_image(databox1, xf.fwd));
return intersect(box0inOUTin, lc);
}The change was in creating a temporary variable to hold the parallelogram. Why that fixed it, I don't know, but I do know that the compiler's error message didn't help me very much.

That doesn't even remotely look like valid code in any C++ standard. Please provide a *complete* test case.
