I guess so.

No, but nobody has taken the time to clean it up.

Same answer as above.

No, this is not enough.  For example, MAC_OS_X_VERSION_10_6 is not defined on 
OSX 10.4, but we use it in the source, so we must define it if not defined.
The define for MAC_OS_X_VERSION_10_6 in nsterm.m is redundant though.

I guess it is not, if indeed that function is available in Tiger and onwards.  
But it might also mean that it is only available in Tiger and not in later 
versions.  I haven't checked.
