I did qualify that this download is unofficial. The site is a place to
upload clang-related patches and builds for testing.

There are different groups of "we" posting all the time on this list,
whether it's Apple, Google, FreeBSD or Debian and I can only speak for
myself and Nuanti.

Nothing's been done. There's been something on the site for probably a year?

Here's the background: We were chatting on the #LLVM IRC channel during
the devmeeting, and put up some balloons on that page to celebrate the
commit you did with Faisal completing C++14.

It was a significant moment for a few of us who made contribution's to
clang's C++0x support, I think possibly before you were around on the
project?

As for the download, a couple of days there was a need to upload test
builds with the patches from the PR, and the site was already there.

A patch adding balloons? I'm not sure what you see on clang.org that's
significant -- it's a homepage for clang-related odds and ends.

Sure, let's do this. Though I don't really feel like celebrating r194188
after this discussion :-/

On the other hand It's been encouraging to hear from people who've been
enjoyed the builds in the meantime and reporting back. The real solution
is to actually get these fixes landed.

Cheers,
Alp.
