Re: Full-featured free Ada 95/2005 compiler?

[anon@anon.org (anon)]

Gnat Pro has extented specifications to meet the DO-178B Level A 
certification for writting program for Avionics systems which the GPL 
does not do.  This is done by adding extra packages and coding 
standards that the Standard Ada does not have. 

The government of most counties have agreed that all programs for 
Avionics must meet the DO-178B Level A certification. Most people 
who use GPL GNAT does not need this level of reliability even if they 
use Ada on a real-time environment. 

Plus, the DO-178B certification is only use for Avionics. There are other 
standards for medical and military and even nuclears power plants that 
GNAT Pro does not have. So unless you are writting an Avionics system 
you do not need the DO-178B certification packages. Then again if you 
do need the DO-178B standard, the company for insurance reasons 
would pickup the tab for the GNAT Pro.

The DO-178B certification package is not free and is one of a few 
reasons that explains why GNAT Pro is so costly!
