The most important check is for header search, but I was hoping it might serve as an overall sanity check for other issues. I already found one issue with i386 that is not exposed with -fsyntax-only. (I’m looking at that now and will fix it if there’s an easy solution.) I don’t feel strongly about this test, so in the interest of reducing testing time, I’ll change it to use -fsyntax-only.
