Another issue is that we might just happen to use the "C" locale when
the AC_TRY_RUN program is invoked, which probably doesn't exhibit the
broken behavior of Mac OS X, since at least with glibc on Linux that
leaves you with a blob exactly matching the original string. Then
again, who knows? The Mac OS X behavior seems totally arbitrary to me.
If I had to guess I'd say it has something to do with their providing
an open standard shim to a UTF-16 based proprietary API.
