egcs is an experimental step in the development of GCC, the GNU C compiler. A bunch of people (including Fortran, Linux, Intel and RTEMS hackers) have gotten together to return to the fundamental idea that code visibility and submissions from the net are vital to the long term improvement of the compiler. They are going to integrate variations and patches to GCC that are floating around, including some front-ends like g77 (Fortran). They are going to work closely with the free OS'es (e.g. Linux, *BSD) where GCC is a critical piece of infrastructure.
