egcs                    1.0.3 (sorry, I wanted to be as
compatible as
                        possible with RH 5.2, so no 1.1.1,
and egcs-cvs
                        is currently not stable enough on
sparc/sparc64).
                        Added a hack, so that if you specify
-m64 on the
                        command line, it will look for a
                        sparc64-redhat-linux compiler
instead (change its
                        default -b and -V settings in that
case).
                        You can freely now compile both
32bit and 64bit
                        proggies (well, 64bit just the
kernel, sorry)
                        just by running gcc.
egcs64                  NEW PACKAGE - This is the latest
egcs-current before
                        reload changes, which is known to
build a working
                        sparc64 kernel.
