Yeah. I keep screwing up and using version(Linux). To match the others, it 
really should be version(linux), but so much code would break at this point if 
changed it that we can't just change it. We could add version(Linux), and 
since it's a standard version defined by the compiler, I guess that the 
compiler could deprecate it. Regardless, the fact that it's all lowercase when 
all of the others (except for unittest, none, and all) begin with an uppercase 
letter definitely causes bugs (for me at least).
