So, something like: -analyzer-opt-ignore-system-headers ?
This would fix my situation, provided I'm willing to go through my build
command and replace several instances of -I with -isystem for the purposes
of analysis. I don't think that would break the semantics of my build, but
I'm not sure you can say that in general. Changing from -I to -isystem will
cause the directory to be searched after all -I directories, so if your
build is order sensitive, that might cause problems.
