No, but is that really relevant? 

The problem was not library linkage, but the fact that 
if an exception was raised in the Ada modules, the 
exception handler would not work -- the whole unit 
would abort.

In fact I was able to interact with ncurses and everything
else C wise, until I did a "raise".
