gnat 3.15p-19 (i386 binary) in ubuntu dapper

 GNAT is a full-featured Ada 95 compiler. A quote from
 http://www.adaic.org says: "Easily reused and maintained, readable and
 user friendly, Ada code facilitates such massive software projects as
 the Space Station and the Paris Metro. It has proven to be
 extraordinarily robust in decades' worth of daily field tests under
 the most rigorous conditions in which millions of lives have been at
 stake." Ada is the language for real-world, mission-critical programming.
 .
 There are currently five variants of GNAT:
 .
  - GNAT Pro, commercially supported and actively maintained.
  - The Public version of GNAT, industrial-strength quality but unsupported.
  - The GNAT GPL 2005 Edition, up-to-date and reliable, but unsupported and
    with a run-time library under pure GPL. The other variants grant special
    permission to distribute proprietary software linked with the run-time
    library.
  - The GNAT Academic Programme, supported, identical to the GPL edition,
    available at no cost only to academics.
  - The FSF version of GNAT, which is part of GCC since 3.1 but where the
    integration with the GCC back-end is considered work-in-progress.
 .
 This package contains the Public version of GNAT. As an alternative, the
 FSF version is available in packages gnat-3.3, gnat-3.4 and gnat-4.0.
