There are a few tests that are listed as failing here for which I have
a patch in the works. I'll be sending those along soon. There are
others where I know what is going on but don't yet have a solution,
and I've included some notes for those. Several still need to be
investigated, mostly in localization and the regex test suite. I think
that many of these failures are due to locale implementation
variations that make the expected test results not match the actual
results. I'm not sure what the best way to make the tests accomodate
this sort of variation might be.

The failures in the unique_ptr test suite are very new and are caused
by a clang crash which I've not yet looked into.

Add a big "why libc++" section to address a pretty major FAQ.
