                 32bit but running on 64bit-capable CPU.

                CAVEAT: This is bit dangerous, as on 64bit OS, if ia32 libs are
                not installed byt 64bit sqlite libs are, then 64bit libs are found
                and when a function is called, segfault will occur!!

                Q: Is there a way how to figure out if the OS itself is 32bit,
                regardles on CPU?"
