Hello.

Thank you for your interest in AArch64 Cygwin.

The changes that has been upstreamed so far are not yet enough to build the package itself nor the toolchain necessary to build it. The minimum allowing that lives in https://github.com/Windows-on-ARM-Experiments/newlib-cygwin/compare/upstream...aarch64-patch-series1-v1 branch. All the changes, we've developed so far are in https://github.com/Windows-on-ARM-Experiments/newlib-cygwin/commits/woarm64/ branch, which is our "develop", and few WIP feature branches in the same repository.

You can build your own Ubuntu (both x64 or Aarch64) to AArch64 Cygwin cross-compilation toolchain using https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/blob/main/.github/scripts/build.sh script, e.g. in WSL. Just change `PLATFORM` variable from `w64-mingw32` to `pc-cygwin`, `RUN_BOOTSTRAP` to `1` and `UPDATE_SOURCES` to `1` in https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/blob/main/.github/scripts/config.sh (those work as environment variables too).

Building x64 Cygwin to AArch64 Cygwin cross-compilation toolchain requires some additional changes that are in https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/compare/main...native-cygwin branch. I generally don't recommend this as it takes around 8 hours on beefy machine while it takes around 2 hours for the Ubuntu one.

Radek
