Thanks for the sound advice. I am sure you are right, 2 Questions:
1. If I am ONLY interested in the compiler, and do NOT want to build libraries, what would be the process ?? 2. I looked at newlib, but wasn't sure of the process of including it as a combined tree .. Which subdir should I move over to the gcc tree ??
