Tsirkin" Our rule right now is to use <> for external headers, "" for internal ones. The idea was to avoid conflicts between e.g. a system file named and an internal one by the same name. Unfortunately we use -I compiler flag so it does not help: a system file doing #include will still pick up ours first. To fix, switch to -iquote which is supported by both gcc and clang and only affects #include "" directives. As a side effect, this catches any future uses of #include <> for internal headers.
