It's a locale issue.  configure scripts default their environment to C
locale, but C doesn't have to mean ASCII.  On my Cygwin, C means UTF-8.
I suppose though that's just because Cygwin changed recently.  Setting
LC_ALL=C.ASCII makes the test pass.

Now, I'm not sure what that means for real-life configure scripts.
IOW, should _AS_SHELL_SANITIZE be fixed, or only this torture test?
Then, is C.ASCII even a portable setting for LC_ALL (and LANGUAGE)?

Thanks,
