Hi Marco,
I upgraded python39-numpy to 1.22.0-1, and failed to import numpy.
It seems that mtrand.cpython-39-x86_64-cygwin.dll does not have
PyInit_mtrand.
Could you check if numpy can be imported in your environment?
working on it.
In theory I have not changed the build between the two versions
but there was a patch in 1.19.4-1 for similar issue.

I have the same problems with the distribution NumPy package, but I can
use a locally-compiled NumPy with no patches. It doesn't look like your
build has any patches either:
https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fpython-numpy-src%2Fpython-numpy-1.22.0-1-src&grep=numpy
so that's fun.
Out of curiousity, what options are you passing for cpu-baseline and
cpu-dispatch?

I don't see the newest cygport in the Cygwin package repository.
I have not found the root cause yet.
As the 1.21.4-1 imports correctly I removed the 1.22.0-1 until I solve
the issue.
I do not see anything obvious in upstream source between 1.21.4 and
1.22.0 that gives me any hint on root cause.
Also 1.22.1 shows the same problem.
I excluded the build chain as rebuilding 1.19.4 worked fine
for all 3.6 to 3.9
Regards
Marco
