Hi! As you may know, I'm working on multiarch cross-toolchains as part of the Google summer of Code (see my previous post for details), and although there is still a lot to do, the project is doing fairly well, and a cross-gcc is already installable and working. I'll proceed with detailed instructions on how to install the cross-compiler, along with some explanations on multiarch itself, and how t

GCC Runtime Library Exception Rationale and FAQ - GNU Project - Free Software Foundation

The licenses for some libraries that accompany GCC have not been changed yet. These libraries are
