It's hard.  IMHO it is a hole in the Xt functionality.

Keep guessing.

If I had to do it I would:

	1- In a separate file include IntrinsicP.h and write a function

		char * XtName(w)
			Widget w;
		{
			return(w->core.name);
			/* Or you could malloc and copy... */
		}
	
	2- Make that file into a .o and link with it.

Yeah, it's a somewhat cluttered approach, but when the Intrinsics 
support the functionality all you have to do is throw away one file and
change your link line.

Small unmarked bills are best...  ;-)

Not easy to do if you want to attach it to the widget structure itself.
In R3 you could take over the extension field, but you might get
clobbered later.  I think that I would use the Xrm database.
