+ * <sys/time.h> overlay for the MontaukOS git port.
+ *
+ * Adds the ITIMER_* selectors on top of the libc header. MontaukOS has no
+ * interval timers, so the port is built NO_SETITIMER=1 and NO_STRUCT_ITIMERVAL=1
+ * -- git supplies its own struct itimerval and a setitimer() that returns
+ * success without arming anything. The selectors still have to exist, because
+ * the call sites name them (builtin/log.c's early-output timer, progress.c).
+ *
+ * What that costs: `git log`'s half-second early-output nudge never fires, so
+ * the first commits appear when the traversal produces them rather than on a
+ * timer. Nothing depends on it for correctness.
