Right? Yes, as Alan said accept4 has been supported in the kernel since v3.2. I'm running udev-208 on a couple of alphas without trouble, so this problem should be fixable. Is it possible that your glibc was built against linux-headers older than v3.2? Seems unlikely, but it's probably the first thing I'd check.
