I may be missing something, but wouldn't the presence of conditional code 
that does or does not use C++11 features depending on whether or not 
they're available undo any readability features that using the features 
enabled?

As I said in the original thread, I'm mostly ignorant of Cmake (which I 
sense you're advocating more strongly for than autoconf).  I'd be curious 
to hear others' opinions on it.
