I have the same problem and a bit more:
I need a unique identifier (for instance a char* name) for most InterViews objects.

I introduced a new superclass called Ident for only two InterViews classes -
Resource and Window. 
The compiler (AT&T 2.1 on a Sparc IPX running SunOs-4.1.2) made no problems
with InterViews 3.1-beta, modified in that way.

The same as me.
