According to my understanding of e.g. K&R, int is to be whatever size is 
the true size of that processor, hence int on a 64bit machine is 64 bit. 
When, if ever, did that purportedly universal, and quite simple, standard 
get changed? It seems to me that int has no business being 32 bits on a 64 
bit machine, in 'C'. Did the ANSI standard specify that K&R were wrong on 
that point and specify some other algorithm for deriving int size from 
true bitsize of a word on the processor? Or are we talking some other 
language (Does even C++ specify a different algorithm for such 
derivation?)
