-// LLVM throws an error if a function with the
-// x86-interrupt calling convention is compiled
-// for a Windows system.
+// The x86-interrupt calling convention leads to the following LLVM error
+// when compiled for a Windows target: "offset is not a multiple of 16". This
+// happens for example when running `cargo test` on Windows. To avoid this
+// problem we skip compilation of this module on Windows.
