BTW, here is an alternative fix (against 7.10.3) that uses the minimum deployment target to determine whether to use the new ’clock_gettime()’ on macOS to avoid the problem I mentioned in my previous message:
https://github.com/mchakravarty/ghc/commit/da87a6551a528d51dfd4277c4468c57d5039ab59 (So far only tested by compiling against the macOS 10.12 SDK w/ Xcode 8 and running it on macOS 10.11.)
