 > Any idea how to fix it?
 I was hoping to see some kind of compiler error or warning in the
 config.log relating to the "checking type of array argument to getgroups"
 test in the config.log, but I don't see anything like that in there, so
 no, I don't have any ideas.

 As I said earlier, the check for `getgroups` is implemented in a standard
 autoconf macro `AC_TYPE_GETGROUPS`, so if it's giving the wrong value,
 then that's where the fix is needed (in
 [https://www.gnu.org/software/autoconf/ autoconf]); it's not something
 specific to rsync.

 We can of course apply a band-aid over the problem in MacPorts by forcing
 the correct value of this check in the rsync port, but any other ports
 that use the same check would be affected as well and would then need that
 same band-aid.
