Both, really. If they have to code up macros to support identical operations
(such as addition) on both platforms, and accidentally forget to use the macro
in some place, then voila: untested code.

You're also forgetting that this isn't high-level programming where you get to
lean on a cross-platform libc or similar. This is literally interfacing with
the hardware, and there are a whole boatload of subtle incompatibilities when
handling stuff at that level.
