Building the latest code in git on Haiku fails with a number of error messages like

int waitForTime(const struct timeval* abstime) const;
This seems to be caused by Monitor.h using struct timeval but not explicitly including sys/time.h. Changing Monitor.h so it conditionally includes sys/time.h on systems that have it resolves the issue.
