In 91f6a7f616b161c25ba2001861a40e662e18c4ad I supported `windows-gnu`
and `windows-msvc`, but I forgot about the last one: `windows-cygnus`.
This LLVM commit [1] introduced all 3. (I wish I had found it before!)
But at least we can use it to ensure I am not missing one now.
This came up in this
GHC has been using a custom triple "javascript-unknown-ghcjs" for their (non
asm.js, non wasm) javascript-emitting kernel-less target.
https://gitlab.haskell.org/ghc/ghc/-/commit/6636b670233522f01d002c9b97827d00289dbf5c
This triple is a bit of an oddball, so the support for it is highly
