A quick google search reveals that NetBSD and FreeBSD use GNU grep, while OpenBSD uses BSD grep, which (at least according to the man page - see http://tinyurl.com/cs2unf) does not support GREP_OPTIONS. It seems that work is underway to port the BSD grep to FreeBSD and NeetBSD. See http://www.freebsd.org/cgi/man.cgi for a comprehensive list of manual pages for many popular unices. It seems that many greps do not support GREP_OPTIONS.
