That is, AFAIK, none of them. OS X version tests are too general to have
meaning outside OS X. Someone could be testing the version to get AppleScript
compatibility, or some Quartz function, or to know whether Carbon APIs can be
used. In many of those cases the answer would be "no" for a GS platform.
My suggestion is to err on the side of false negatives ("you said we had to do
this instead of that, when both work") rather than false positives ("you said
we could do this but we can't").
Cheers,
Graham.
