Oh, oops, I wasn't reading carefully enough.

I think an experimental C1x mode would be the best way to deal with
this, similar to the C++0x mode.  I don't think a separate Unicode
command-line switch is really necessary; it might be simpler to have a
"UnicodeTypes" boolean in LangOpts so that you don't have to write
constructs like "if c++0x or c1x" all over the place, though.
