Absolutely right! Moreover, this approach provides developers on a new target (which already has a C compiler) immediate ability to write and test code. If as the project develops it appears that better code efficiency is required, they can then go the (more expensive) route of commissioning a new target for GCC. But, in the mean time, they do have a useful compiler for testing. Art Evans
