My concern is that different operating systems have done different
things with 32-bit and 64-bit libraries, even within the space of Linux
distributions.  Rather than a solution narrowly tailored to one
operating system, I would like a plan which can cover a broad range of
operating systems, preferrably one which doesn't add a lot of complexity
to the code.
