There is a new pull request by ericonr against master on the void-packages repository

https://github.com/ericonr/void-packages pixman
https://github.com/void-linux/void-packages/pull/25301

pixman: update to 0.40.0.
Update links, simplify musl patch.

---

I'm not sure I understand the musl patch. The main thing with musl is that thread stack size is small, so putting the array in thread storage seems worse than leaving it in the main stack.

A patch file from https://github.com/void-linux/void-packages/pull/25301.patch is attached
