> A couple of days ago, that's exactly what I did. It turns out that it's not a huge deal to compile gcc with a prefix which will put it off to the side and then just drop the entire mess into that directory. You can then just do /path/to/your/new/g++ and you'll have the new compiler working for you. It'll gobble up the new syntax and will be happy. I've been there, and it's not fun. And, been down the path of options the author enumerates after this statement. Short of it is, on Linux (and I'm sure it's likely the same on BSDs & Mac), if you're not using the system supplied compiler, you're in for a world of hurt. You will have to build everything you depend on from scratch with your custom compiler. That said, it's possible. Just not fun, or user-friendly.
