Bazel build on windows fails with error from swift #8301
Description
I'm not sure if it's supposed to work, but the bazel build of latest on windows is broken:
git clone flatbuffers
cd flatbuffers
bazel build //...

Error in fail: ERROR: rules_swift uses Bazel's CROSSTOOL to link, but Swift requires that the driver used is clang. Please set `CC=clang` in your environment before invoking Bazel.
We have a requirement to compile the flatbuffers library with msvc, so switching to clang is a non-starter for us. Is swift a real prerequisite for C++?
