gcc47-pr50888.patch

Untested fix.  Checked all locales on my F16 box and in all of them isspace
is true only for these 6 characters and nothing else (iswspace accepts various
other characters, but isspace works on single bytes only and the other
characters are multi-byte.

Yes, we could perhaps define __cxa_call_unexpected instead, but we'd really
want to make sure it is hidden visibility, in order not to override the
libstdc++.so __cxa_call_unexpected.  And not all targets support hidden
visibility, so it would turn into a portability nightmare.
