Or, how much feedback have you given them about why their product is unsuitable for you? They won't fix it if they don't know it's broke. > Gnat (professional or public version) is too far from being suitable > for us Have you done a formal evaluation process with ACT? They will give you free support for a limited time, while you use GNAT for your system. They will help you fix or workaround any problems. In my experience, they offer far better support than any other Ada company. > So compiler availibility could become critical sooner than you think Ok.
