In principle it should be possible to start from a vendor C++ compiler. Of course we will have to test in order to see. > What is the earliest release of G++ that will allow GCC to bootstrap? Another thing that is worth testing. Right now I would anticipate that even fairly old releases of G++ can bootstrap GCC. However, we will need to decide what old release we want to ensure works. Ian
