Thanks for the report; right you are.

This error was introduced with the most recent update to cpuset.h.  There is a 
public-visible mirror of the Cygwin tree at
     https://github.com/cygwin/cygwin/blob/main/winsup/cygwin
and the problematic file can be found at
     include/sys/cpuset.h
within.

Your bug report and proposed correction are all we need for the issue you ran 
into.  I'll submit a patch shortly.
Thanks again,
