- * We want to define GOOD_SELECT if the last argument of select(2) is
- * modified to indicate time left. The code will deal gracefully with
- * the other case, this is just an optimization to reduce the number
- * of system calls per input event.
- *
- * In general, expect System-V-like UNIXes to have this behavior and BSD-like
- * ones to not have it. Check your manual page. If it doesn't explicitly
- * say the last argument is modified, assume it's not.
- *
- * (We'd really like configure to autodetect this, but writing a proper test
- * turns out to be hard.)
