I just saw this and wanted to ensure it was recorded. I haven't created a repro since it should be apparent in any example that upgrades to bazel-8.3.0

This will be fixed by the next bazel-skylib release: https://github.com/bazelbuild/bazel-skylib/pull/574

We're seeing the same warning in rules_wasm_component issue #32: https://github.com/pulseengine/rules_wasm_component/issues/32

The warning appears when using build_test from bazel_skylib with Bazel 8.3.0:

WARNING: target depends on deprecated target '@@bazel_tools//src/conditions:host_windows_x64_constraint': No longer used by Bazel and will be removed in the future.

For now we've added a comment referencing this issue. Looking forward to the fix!
