The correct fix is for GCC not to intentionally choose to rely on
implementation defined behaviour when using the "C" locale. GCC can't
portably assume any other locale exists, but can portibly and easily
choose to get consistant output when using the "C" locale.

I don't see how a defect in POSIX is exposed here. Nothing in
the standard forced GCC to output multi-byte characters when
nl_langinfo(CHARSET) returns something like "utf-8". GCC chould just
as easily have choosen to output these quotes as single-byte characters
when nl_langinfo(CHARSET) returns something like "windows-1252", or some
other non-ASCII single-byte characters when it returned "iso-8859-1".
