I'll pipe up here.

Chris is correct.  You either need to base off the BSD version or else 
you must write a new one based on the API description).  Newlib has 
changed a few code licenses in the past with author permission, but not 
for FSF contributed works.  The following Freebsd implementation seems 
fairly straightforward.  Is there anything missing?

strcasestr.c:
http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/string/strcasestr.c?rev=1.4;content-type=text%2Fplain

If not, I can add it the repository.
