This was enabled in an updated Cygwin uname(2) "syscall" in 2019 
January, but not visible to older utilities built against the older API, 
only exposed when coreutils was rebuilt, as intended:

* each string was lengthened from 20 to 65 bytes, and domainname added;
* for kernel, added the Windows build number, and restored the 64 after 
WOW, removed for Windows 10;

* for release, dropped the "s" snap indicator, and the API info in 
parentheses, added a dash and the API minor release, dot and 
architecture, and a ".snap" suffix for snapshots;

* added UTC after version/date;
