Eclipse Community

Somewhat recently, I've made a version of QT 5.16.15 compatible with Windows XP. It works for the most part, however there are some slight issues that I don't know how to fix yet.

It appears to work pretty well in the limited testing I've been able to do with it. The issues aren't that major, maybe outside of this below. (please help fix)

The reason this is here under Research Network is because the issues, and maybe the possibility of a QT6 for XP. I haven't looked into QT6, but I believe if I were to try, I'd likely be able to do it. However the current issues, I'm not sure how to fix, and that's more what I want the community to help with. Although having a community QT6 for XP would also be nice, as I'm not sure if I'd ever get around to making it if I can just backport to QT5.
