A relevant change is a bump from MSVC 19.41.34123.0 to 19.42.34433.0

Probably this change

I've created a ticket here.

Thanks. I've downloaded the latest (=10.0.26100.0) Windows ARM SDK using this script and the um and ucrt directories are empty indeed.

Has anybody seen an announcement about Windows on 32-bit ARM being deprecated?

I think I fixed this in bd57cfd by pinning the Windows SDK version to 10.0.22621.0 when building ARM32 binaries.

Other SDL libs need similar treatment, including active branches, and including sdl2-compat which suffers from the issue.
