No need to worry about that, it's just a way to coerce ICU's build
system into behaving well on Windows. Conan uses Msys2 as a build
environment for projects with *nix lock-in, which produces native
binaries without the cygwin shenanigans.

That's a tough one. I see you commented on the issue regarding this:
https://github.com/libffi/libffi/issues/500#issuecomment-671037484

I'm not sure what should be done in this case. I have a feeling the
Conan team would not welcome such a partial feature patch. Maybe having
an Artifactory server on php.net, where a custom recipe is hosted would
solve this. I'm sure if the Conan team was contacted about this, then
they would be glad to help.
