For the most part this is up to the developer and their ability to avoid
non-portable system and library calls. There are other ways to make code
non-portable, but those are the usual culprits. Ada makes this easier
than many languages because of standard support for things like
multitasking that many other languages rely on the OS for.

Currently the (arguably) worst culprit is the user interface. There are
some portable GUI libraries out there, but they each have their problems
(lack of widgets, small number of ports, etc). And even that won't help
you if you want to run your program on a text-based system.
