This is the license for the LLVM code, build script and other files included in the tarballs from llvm-mingw project use ISC license: https://github.com/mstorsjo/llvm-mingw/blob/master/LICENSE.txt

How should we handle that?

(I would ask Wesley/David for the licensing part.)

Hopefully they won't mind summoning them here.
@wesleywiser @davidtwco can you help us here?

Thinking more about it, llvm-mingw consists of: prebuilt LLVM binaries + headers, prebuilt mingw-w64 + headers, prebuilt dependencies of LLVM like libffi, prebuilt binaries from llvm-mingw repo + shell scripts + Clang config files (they are located here: https://github.com/mstorsjo/llvm-mingw/tree/466fbcb68f024758c20cbea9544a44d1e5194bdc/wrappers), and apparently now it also includes prebuilt Python.

llvm-mingw's LICENSE.txt states:

The final built toolchain is covered by the licenses of the individual
external projects, primarily LLVM's Apache 2 license with LLVM exceptions.

If the license of the artifact is Apache 2 w/ LLVM exceptions then I expect this would be fine.
