To put a long story short: I run sparse against netbsd tree. To be
slightly more elaborate, I should mention that I wasn't able so far to
fully appreciate the beauty and elegance of certain design decisions
of the project in question. Nevertheless, I'm seeing different reports
from gendep and compilation runs.

Well, that aside, the overall build time significantly increases with
having to run sparse twice. Same warnings/errors are reported twice.

I still think that sparse has no business validating any code when
cgcc is called in -M mode; all those files are going to be compiled
later on anyway. And it's the compilation stage where warnings are
desirable.
