Hi,

We have a strange issue with building pyFFTW with Numpy 2.0 on Windows. I observed it before when a build in the CI tried to use Numpy 2.0. The solution was to pin the Numpy version used for the build to <2.0.

However, now I'm trying in this PR (https://github.com/pyFFTW/pyFFTW/pull/383) to make pyFFTW compatible with Numpy 2.0. With few simple changes, it works well on Linux and Macosx but not on Windows.

The meaningful part of the log seems to be:
