Or at least, I can't find any reference from that as to *why* we bootstrap and what we gain by doing so. I've read the install doc and I can't find what I need. Two reasons: 1. We compile the compiler with itself. This is a very good way to test the compiler we just built. 2. Newer versions of gcc have better warnings and checking and (hopefully) generate better code. So the resulting compiler should be faster. Andrew.
