This can happen if you update a package without updating its 
dependencies.  For example, the dependency might have introduced a new API.

It is in cygwin1.dll as of cygwin-2.10; see 
https://cygwin.com/cygwin-ug-net/ov-new.html.

You need to update the cygwin package.  For best results, you should 
update all of your installed packages to their current versions.  (If 
you're running setup with the --packages option to update or install 
certain packages, then it's a good idea to also use the --upgrade-also 
option.)
