Ungh... yes, it's defined by default, but it clearly still requires
keeping the #ifdefs in there in order to still build if someone manually
undefines it. Was hoping to avoid the #ifdefs entirely - perhaps the
existing #ifdefs should just be removed? If it's been enabled since 8.1
it seems unlikely to be causing anyone any issues.
