+Subject: [PATCH] os-compatibility: define CLOCK_BOOTTIME when not available
+
+CLOCK_BOOTTIME is supposed to be provided by the C library headers,
+but uClibc 0.9.33.2 does not provide it. Instead of depending on an
+uClibc patch, let's make Weston define it to the right value when not
+already defined by the C library.
