Are you referring to a runtime issue?, since a later SDK has been needed from wine-5.8.
Yes. That function will be weak-linked, which means that on 10.8 and 10.9 it will be
NULL. Calling
it without checking for NULL will cause a crash on those systems.
I was obviously expecting this to not be a problem since fstatat is
already used in fd_is_mount_point(), is there an existing example of
how we like to work around a function that's weak-linked and possibly
NULL?
See lines 92-96 of dlls/ntdll/unix/sync.c. Though in this case, I don't think that
method will be acceptable here, since mach_continuous_time() is unique to macOS and is
used in macOS-specific code, while fstatat(2) is a standard POSIX function used in code
compiled everywhere.
