+# Never replace this with the Ada compiler in the gcc tree. They are based
+# on the same source but this is the official validated compiler from ACT.
+# The one in gcc (3-branch) is currently broken!
+# If you want to try that one install it under a different name and use
+# gnatmake --GCC=othername (if you use gnatmake).
+# The official statement from ACT is that they will continiue to release
+# GNAT, so they will release a version based on gcc 3 when it is working.
+#
+# It is possible to at least install this on sparc too, I have seen
+# unofficial bootstrap compilers for ppc as well. As I don't have access to
+# a sparc or a ppc running linux I won't try to add support for them.
+# If you have access to any of these it should be fairly easy to add support
+# for it.
