The warning that lint is giving you is based on the fact that you are casting
a character pointer (returned from malloc) into another pointer type having
more stringent alignment requirements.  Malloc does guarantee that all 
pointers it returns are properly aligned to use with any data type but lint
does not assume this since "malloc" is just another function (you could write
your own version you know).  Your best bet is to just ignore the warning
since you are NOT in reality going to have any problems from this!
