GNAT AUX is based on the trunk version of Free Software Foundation's GNU Compiler Collection. It carries with it the GMGPL license, the modified version of the GPL that exempts generic instantiation from resulting in a GPL-licensed executable. This version of GNAT also carries with it the GCC Runtime Library Exception, so the resulting binaries have no licensing requirements. Binaries produced by GNAT AUX should be handled the same as binaries produced by any FSF GNAT compiler. GNAT AUX implements the full Ada-83, Ada-95, and Ada-2005 language standards. It also implements some features of the draft Ada-2012 standard, which are optionally accessible via the -gnat2012 switch or Ada_2012 pragma. WWW: http://www.dragonlace.net/
