KaDiWa4 opened issue #3634:

Currently, the file crates/jit/src/unwind/winx32.rs serves no purpose. In #3180 the other two unwind implementations (winx64.rs and systemv.rs) were rewritten, but the stub in winx32.rs was left unchanged. This means that the crate doesn't compile on 32-bit Windows. The file could be replaced with a new stub or removed entirely, I don't know.

Cranelift currently doesn't have an 32bit x86 backend. Only x86_64 and AArch64 are currently supported. See https://github.com/bytecodealliance/wasmtime/issues/1980.

Then I guess it would make sense to remove the file so it shows the [unsupported-platform error][source] when trying to compile.

Yes I think this code is historical and may have worked at one point but no longer does. I think it would be fine to move it to an unsupported platform as you've found.
