GNAT is an open source compiler for the Ada programming language which forms part of the GNU Compiler Collection. It supports all versions of the language, i.e. Ada 2005, Ada 95, Ada 83 and Ada 2012.
Originally its name was an acronym that stood for GNU NYU Ada Translator, but that name no longer applies. The front-end and run-time are written in Ada, except for a few machine dependent parts that are written in C to aid in portability.
While the existing OS/2 versions work well, there was lot of work put into the OS/2 port including rewriting large portions of it.
An updated version is unlikely since the main maintainers of the code removed the OS/2 branch from the official tree in 2010 and recreating it would be a lot of work.
