In a word yes and no.  There is no way around declaring the
function, but the proper declaration is

	extern Window window_create(Window, caddr_t(*)(), ...);

If you are running cfront 2.0, then you also need to wrap this declaration
between 
	extern "C" {
and
	}

By declaring functions as func(...), you are defeating one of the purposes
of function prototypes, verifying the application is using the proper
argument types.  I have a complete (and untested) set of sunview header
files that have been C++'ified.  If it is legal for me to post them,
I will.
