As seen in the following thread, the protobuf team is planning to stop supporting the combination of Bazel and cl.exe due to well-known its path length limitation. * protocolbuffers/protobuf#20085 As a preparation before switching to protobuf v30 (google#1177), let's explicitly add a commandline option as explained to continue using this combination as a short term solution. This commit should have no impact on Probobuf v29.x.

This issue is a placeholder for gathering feedback on an upcoming breaking change
Due to persistent issues with MSVC's path length limits, we've decided to drop support for Bazel in 34.0. Starting in 30.0, you will need to explicitly set a flag
--define=protobuf_allow_msvc=trueto use this combination. Our recommended alternative is clang-cl, which we will officially support going forward.If you're not using Protobuf-C++ and you've hit this issue purely because you need to build protoc from source, just use the opt-out flag for now. We will be releasing a prebuilt protoc toolchain by 34.0, which should decouple you from this.
