What rule?  I've dealt with systems that are ILP32 and LP64 (which  
one is determined by compiler flags).  AIX is one of them, and if my  
recollections of porting are correct, Linux on AMD64 is another.  The  
assumption that many 32-bit developers seem to hold that an int is  
the same width as a pointer causes porting delays.
