, up to its latest version (4.5). GFortran is also compatible with most language extensions and compilation options supported by g77, and many other popular extensions of the Fortran language. Since GCC version 4.0.0, released in April 2005, GFortran has replaced the older g77 compiler. The new Fortran front-end for GCC was rewritten from scratch, after the principal author and maintainer of g77, Craig Burley, decided in 2001 to stop working on the g77 front end. GFortran forked off from
