I would recommend that line 58: {{{ # if ((__GNUC__ == 4) && (__GNUC_MINOR__ >= 8)) || (__GNUC__ > 4) }}} is changed to {{{ # if ((__GNUC__ == 4) && (__GNUC_MINOR__ >= 8)) || (__GNUC__ > 4) || __clang__ }}} Certainly this removes the errors from my machine but i've been unable to ascertain whether or not this would cause massive issues on other versions of llvm or indeed how to use macros to get the version of llvm in use."
