libhpcalcs: portable (Windows / MacOS X / Linux) connectivity kit library

[LarsF]

I have manage to compile the package on my mac after som problems with libpng12. Receive files seems to work, send a file crash test_hpcalcs, but after reading the previous messages, that seems to be a bug. But i wonder, is it possible to list the content on the calculator, so get a list of programs/apps and so on?

btw, nice initiative to make something like this for us that don't run windows.
