portability of GNU+Linux

I like most of Glyn's articles, and I appreciate that he calls the operating system "GNU+Linux" instead of just "Linux". I even overlook that he calls it "Open Source" instead of "Free Software".

The article talks about the portability of the Linux part of the GNU+Linux operating system, and how important it was that the Linux kernel was ported to Alpha so many years ago. This is true, it really was important.

But what about the portability of the "GNU" part of the operating system? gcc, coreutils and bash have always been portable, and run on different architectures and even on different operating systems.

The portability of the GNU portion of the GNU+Linux system is equally important (if not moreso), and deserves at least one line in the article.
