Let is just agree that it is a feature of the source code that prevents 
compilation under certain circumstances.

My question was if there anyone interested in fixing it, and where I 
might file a request.  Although the problem is on the Apple branch, 
they are hardly going to be interested in fixing something they don't 
use.  The FSF people might well argue that it is not broken on the 
HEAD.

Ideally of course there might be a configure option to build 
gnu-libobjc on Darwin.

I tried to analyse the problem myself, but it is way out of my league.  
I am an engineer turned finance academic not a computer scientist, and 
I really have little idea of compiler internals.
