--- Comment #18 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
> This failure is simply a consequence of broken libgcc on Darwin: this 
> libgcc is not able to get exception table addresses and therefore cannot 
> propagate exceptions.
>
> Any program (that uses exceptions) and linked with -static-libgcc on 
> Darwin will also fail.

In the commit r247301 I see in gcc/ada/gcc-interface/Make-lang.in

Isn't this wrong for darwin?
