Any chance of a Windows build?

### Comment:

Is there any chance of a numdiff package for Windows? This seems like a pretty small codebase, shouldn't be too much work to get it to compile (?)

Start by reviewing the numdiff-feedstock repository's build configuration and package metadata to determine how the current package is built and what Windows support would require. Confirm whether a Windows build is feasible, then document or implement the required packaging changes and verify that the feedstock can build successfully on Windows.
