I don't think this has anything to do with Windows10 or 11, but with the
version of procps-ng you're running.

I tried vmstat from procps-ng-4.0.2-1 on both, W10 and W11, and I got
the above error in both cases.

I switched back to procps-ng-3.3.17-1 and vmstat worked fine on both,
W10 and W11.

I ran vmstat from procps-ng-4.0.2-1 under GDB and found that this
vmstat tries to dynamically load libnuma.so or libnuma.1.so, both
of which are naturally not available on Cygwin.  So I guess vmstat
from procps-ng-4.x still needs another patch.

Achim?
