Confirmed. The problem is in gcc/incpath.c
/* If -Wmissing-include-dirs is given, warn. */
cpp_options *opts = cpp_get_options (pfile);
if (opts->warn_missing_include_dirs && cur->user_supplied_p)
cpp_errno (pfile, CPP_DL_WARNING, cur->name);
cpp_errno is not designed to pass down the warning option. All cpp_errno using
CPP_DL_WARNING should use a new cpp_warnno modeled after cpp_warning that
passes down the appropriate reason (option) for the warning. I am sure there
are more cases of this.
