According to http://man.openbsd.org/regex.3 --

 There is one known functionality bug. The implementation of
internationalization
 is incomplete: the locale is always assumed to be the default one of IEEE
Std
 1003.2 (“POSIX.2”), and only the collating elements etc. of that locale
are available.

Wouldn't that mean this test should be expected to fail on openbsd?
