You may not care about this (most sane people don't), but pointers in
ILE on the iSeries (formerly known as OS/400) are over 100 bits....
Can't remember if it's 128 or something bigger than that, but it will
throw you for a loop the first time you port C code.  Especially C code
that prints pointers with "%x" instead of "%p"....
