The vast majority of "libraries" written for GNAT aren't portable enough to 
use on other compilers, even if they only use Ada 95 features. In my 
opinion, a library isn't portable unless it is compiled on at least two 
different Ada compilers.

Supposedly, the IBM compiler supports Ada 2005. (They issued an announcement 
to the effect last year.) It might be hard to buy a copy, though (it's hard 
to find it on their website).

The latest version of Janus/Ada supports all of the Ada 2005 syntax and some 
of the features. (But nowhere near all of it yet.)

So that's at least 2.1 commercial compilers (counting GNAT).
