The resulting string is correct, and the grep simply doesn't work
because you have a localized gcc. The addition of grep here was
done to support clang (see c/s 22985:d8ea33e7af7e, author
Cc-ed). It's not clear to me how to get around such translation
issues (Tim - could you explain what output clang generates that
made the use of grep necessary?), nor do I have a clue why the
sed invocation would complain about an unfinished command
(from what you provided I'd suppose that it would end up with
an empty replacement string, which ought to be fine).
