Bruce, I believe the problem is that these specific instructions are *unusual*. Given that we install these three packages separately later in the book, an instruction to extract them into the gcc source directory seems wrong, and should have an explanation as to why it's the correct thing to do. I don't mean a clarification of the instructions - I mean a statement of why the instructions are there at all. Consider, we have a short explanation for each of the options passed to configure, and why we have to fix a missing symlink after the install. But we don't give anything for the tar commands, beyond a vague comment about "will be built with GCC". Why do we extract these files into this directory, then apparently do nothing with them? My thinking here is that our readers are smart people. And smart people don't just follow the instructions blindly - they see odd stuff like this, and wonder if it's an error in the book, wonder if those packages should have been installed 'properly' like in Chapter 6...
