Description of problem:
Extended regex handling is enabled with -r command line option on linux.
NetBSD and FreeBSD use -E, but also provide -r for compatibility.
Mac OS X only accepts -E. As a result, building on Mac OS fails early. (There may be other issues with building on Mac OS.)
In any event, it's possible to do the job with an ordinary regex, extended regex isn't necessary.
