Yes, not surprising. I just looked at the implementation in glibc, which
I assume you are using, and it seemed rather basic. The one in NetBSD's
libc looks much more efficient.

See

http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/libc/string/strpbrk.c?rev=1.1.2.1&content-type=text/plain&cvsroot=glibc
and
http://cvsweb.de.netbsd.org/cgi-bin/cvsweb.cgi/src/lib/libc/string/strpbrk.c?rev=1.16;content-type=text%2Fx-cvsweb-markup

Not that what you've done isn't good, if a little obscure (as is the
NetBSD implementation)

cheers
