Ideally, we should run coverage runs on different systems (Unices, Windows...) and merge the results together, so that we know which paths are really uncovered.
I don't that is easily possible. The coverage report depends on GCC and its gcov extension -- so much for Windows. I also don't know if gcov supports cross-profiling on varying platforms and operating systems.
By the way gcov understands preprocessor output. It doesn't report lines as uncovered when the lines or functions are #ifdef-ed out.
