When using scan-build, you're often going to want to use it in the context of a Nix expression with buildInputs, and the default wrapper scripts will put things like include locations for those inputs $NIX_CFLAGS_COMPILE. Thus, scan-build also needs to pass them to the analyzer - while the link flags aren't relevant, the include flags are. This is because the analyzer executable that gets run by scan-build is *not* clang-wrapper, but the actual clang executable, so it doesn't implicitly add such arguments. The build is two-stage - it runs the real clang wrapper once, and then the analyzer once. Signed-off-by: Austin Seipp <aseipp@pobox.com>
