+GCC 3.3 triggers code generation bugs in earlier versions of the GNU
+compiler (especially GCC 3.0.x versions), which lead to the miscompilation
+of the stage1 compiler and the subsequent failure of the bootstrap process.

+that compiler with the base compiler and then use it to bootstrap the final
+compiler.
