This fixes the commit d6523202 that replaced incorrectly the Darwin
vesion numbers by the same but 10.<darwin>, which is not correct because
they don't match, eg. OS X Lion 10.7 has Darvin OS version 9. Also <=
was replaced by ifndef, which effectively needs version +1, so
original OS_VERSION_MAJOR<=11 (Lion 10.7) needed to be rewritten "ifndef
__MAC_10_8".
Note that since the affected macOS versions are very old, this was only
a minor issue (UG wouldn't be perhaps even possible to compile there).
