The license, which is apparently the zlib/libpng license (from the
project webpage) reads:

2. Altered source versions must be plainly marked as such, and must not
   be misrepresented as being the original software.

3. This notice may not be removed or altered from any source distribution.

As such, I believe that is fine wrt FE inclusion. The program as far
as I can tell doesn't use any patented compression schemes. I'm sure
other members of the list will verify/dispute these observations :)
