Thanks!

Argh! Therefore, since not-installed locale data leads to an exception,
I can simply wrap a set of std::locale(name) in a try/catch, and, either
output << "YES" in the try, or "NO" in the catch. Makes sense?

Any hint about the best way to look at the output? Or the idea is
redirecting to a file and then using "string first" (I see that in a
check part of v3-build_support) on it?

Thanks a lot in advance,
Paolo.
