First one is more readable.

I think maybe the version syntax could be expanded to mean 'or' with commas.
i.e.

version(linux, darwin, bsd)

And forget any other logic syntax (ands, less than, etc).  I believe the 
current method does a good job of preventing convoluted version statements, 
but I think the 'or' is a very common requirement, and does not detract from 
the readability.
