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
