Re: disruptors of & inventory of Ada compilers and latest their era of ISO8652 compliance

Green Hills AdaMULTI still only supports Ada95 with no sign of it ever going past that. Most recent announcements only focus on updates to their C/C++ products, which gives the impression that they barely maintain AdaMULTI. Of course I would love to be wrong about that, but I wouldn't hold my breath.
