Actually, that code isn't portable.  What if sizeof() returns a long?
It often does.  Of course, it is often the case that int == long, so
on most compilers you won't notice the difference.  I really don't
know how to make a piece of code like the above portable, unless you
say things like

	   printf("An int is %ld bytes\n",(long)sizeof(int));

Yeah, that should do it.  Or should that be unsigned long?  Ahhh, the
joys of portable programming...
