How does POSIX differ from Single UNIX in this respect? From the
latter I can possibly deduce that it's undefined.

I'm not sure I get it. Do you mean as in "s/foo[\/]bar/xxx/"? If so,
this isn't allowed by SUS ([\/] means backslash or slash, not just
slash).
Anyway, the solution in this case is simple, just change autoheader.
