A guess: malloc/free/atexit all take pointers as argument, and hence 
prototypes were required for correct behaviour on systems where ints and 
pointers are different sizes.

That is no reason to refuse an abort prototype though.  Eliminating 
warnings from the build is always a useful thing to do.  Want to submit 
a patch?
