Another thing with unsigned types – cinterop now generates a mix of Int and UInt constants:

...
const val WS_OVERLAPPEDWINDOW: Int = 13565952
const val WS_POPUP: UInt = -2147483648.toUInt()
...

...which is a bit cumbersome to use. Is there a good way to pass a list of arguments to a function where each argument can be either Int or UInt? Or can cinterop be improved for these cases?

const val WS_OVERLAPPEDWINDOW is special: you can pass it to interop function expecting UInt. Does it solve the problem?
There is also an explicit way to convert between integer types, see convert function here: https://github.com/JetBrains/kotlin-native/blob/master/INTEROP.md#portability

You mean passing it to CreateWindowExW? But that's the case with all the WS_* constants, most of which are still Int.

Ah. Yes, that's the real problem – I can pass e.g. WS_MINIMIZE or WS_OVERLAPPED but not WS_MINIMIZE or WS_OVERLAPPED.

...but also the fact that the constants are of mixed types. In my actual program, I do WS_POPUP or WS_BORDER or ... which doesn't work anymore without first converting either WS_POPUP or all the other flags.
