Comment (by howarth@…):

 This isn't a new issue because the changes proposed and added in r98265
 never worked in the first place.[[BR]]
 The documentation of the configure options in libstdc++-v3/configure[[BR]]
 [[BR]]
   --enable-libstdcxx-time[=KIND][[BR]]
                           use KIND for check type [default=no][[BR]]
 [[BR]]
 clearly show the current usage is faulty. Also a cursory check of the
 libstdc++-v3/config.log would have[[BR]]
 shown that --enable-libstdcxx-time=yes also is broken on darwin because
 this option is currently linux-centric[[BR]]
 and depends on the presence of posix timers.
