I was able to build a working clang/clang++ environment and then reproduce your 
report.  A potential solution was discussed on the cygwin-patches mailing list.

Just a quick note to say the root cause has been fixed; the next version of the 
Cygwin DLL (3.4.8) will include the fix.  If you need the fix urgently you can 
find a replacement for your /usr/include/sys/cpuset.h at
https://github.com/cygwin/cygwin/blob/main/winsup/cygwin/include/sys/cpuset.h
I would suggest moving (with 'mv') your existing file out of the way but keeping 
it around in case of any mishap getting the replacement.

Thanks again for reporting this issue,

..mark
