The AFL does have attribution issues due to clause 1c), which puts rather  
restrictive conditions on the license the binary copy is distributed  
under. 1C is also what causes it to be incompatible with other licenses,  
such as the GPL. Also, the AFL requires (clause 3) every program contain a  
copy of the AFL licensed source code.
