peanut gallery vote, but I'd go option 1 or possibly option 2. If you 
compared the time/value of effort for improving something cygwin 
specific vs say native compatibility.. Is cygwin really that important 
of an investment?

If implementing a stable __thread for cygwin takes 1 day I doubt you'd 
even ask - if you're talking about 2-3 weeks of work and you're asking 
for feedback - I'd go with someone which has more value. I personally 
don't see cygwin support being clang's sweetspot or "killer" feature on 
Windows.

If there's no downside and it's just code churn - is there a deeper 
question here?
