Although I'm not sure how valuable Cygwin support it is, at least the 
release notes need mention that Cygwin is not supported by design from 
1.4.0

>From the description of the changeset, looks like remove the supporting is 
not intended by the author

Thanks

I agree with Sean - using virtual box on windows and using linux vm is a 
lot easier than trying to circumvent the cygwin oddities. a lot of 
functionality might not work in cygwin and you will end up trying to do 
back patches. Unless there is a compelling reason - cygwin support seems 
not required
