validation failure on Mac

Hi devs, Trying to validate with tonight's HEAD (+ my local changes) on a Mac yields libraries/time/lib/Data/Time/Clock/Internal/SystemTime.hs:22:7: error: error: 'HAVE_CLOCK_GETTIME' is not defined, evaluates to 0 [-Werror,-Wundef] | 22 | #elif HAVE_CLOCK_GETTIME | ^ #elif HAVE_CLOCK_GETTIME ^ libraries/time/lib/Data/Time/Clock/Internal/SystemTime.hs:70:7: error: error: 'HAVE_CLOCK_GETTIME' is not defined, evaluates to 0 [-Werror,-Wundef] | 70 | #elif HAVE_CLOCK_GETTIME | ^ #elif HAVE_CLOCK_GETTIME Is this related to the recent change from #ifdef to #if? Thanks, Richard
