In the mid 90s I wrote and supported a C++ program for moving around and processing data in a semiconductor factory. It ran on Windows and two different flavors of Unix. Half of my time was spent recompiling/relinking and trying to keep up with the upgrades of the few libraries I've used. When Java came out it was so liberating - I'd write a new version of the software on my laptop and ship an update to a client with HP Unix and it would run without a hitch. I doubt that there's still a lot of use of C++ for entire applications. I suspect it's mostly used in performance critical components.
