It sounds to me like there is no difference.  Notice how his example
ldd output shows dependencies on specific .o entries within the
various .a files that reside on the system, rather than on the .a
files as a whole.  If those entries had been statically linked then
they wouldn't have shown up in the ldd output at all.

So the difference is no longer between static libraries and shared
libraries -- they're now just libraries.  The only difference is how
you link to them.

What IBM has done here is very sensible, and is really what the other
Unixes should have done from the beginning: a library is just a
library, and what differs is how it's used.
