In OS's like unix (dont know about windows/dos) the machine code has
absolute adresses. This works because there is a virtual address space for
each process. But if a shared library is used, it cannot use absolute
addressing, since othersise it might collide with another shared library.
Hence it has to be independant of where in memory it is loaded. And data has
to be accessed relative the program counter. Code with this property is PIC.
