Those should be included already though in
https://github.com/geany/geany/blob/master/scripts/gtk-bundle-from-msys2.sh#L251
we still have "win32". Maybe I missed to update ir accordingly.

I'll have a look at the weekend.

Ohhhh.
Did you try Geany's spawn API (`spawn_async_with_pipes` etc.)? IIRC
these use Windows native APIs on Windows and maybe this helps.

Admittedly, I have no clue about LSP but some how intuitively I assumed
the client and server communicate via network.
Could this be a solution, to (at least on Windows) have the plugin talk
to the server via TCP/UDP/whatever network protocol?
