In this particular case the tested functionality is not provided accross

issue, namely that the fallback regex lib we provide doesn't support
REG_STARTEND.

We're currently providing the GNU regex library, it seems Mac OS X and
FreeBSD ship with a regex library that has REG_STARTEND (according to
`git log --reverse compat/regex` the current library was added because
of incompatibilities on OSX, but those were since fixed in
310e0216c8).

If the FreeBSD and Mac OS X implementations are good enough we could
just swap the GNU one for the FreeBSD one
(http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/regex/). Is there
any reason not to do this, or would a different regex library be a
better fit?
