I can vouch for the fact that this works on our Debian server. It's a bit 
annoying to have to add code (as it has to be removed again when using the 
same code with other Ada compiler (Janus/Ada in my case), but it works and I 
couldn't really use Ada without it (too used to the Janus/Ada version). At 
least in most cases there are other things (like rep. clauses) that need 
change as well.
