This new version breaks the build of protobuf-c. You can
reproduce the issue with the command:

make host-protobuf-c

It fails with the error:

protoc-gen-c/c_bytes_field.cc:97:24: error: ‘const class 
google::protobuf::FieldDescriptor’ has no member named ‘label’; did you 
mean ‘Label’?

See also:

I'd like to merge that patch only when protobuf-c will be
able to compile with this new protobuf version.

Could you have a look, please?

Best regards,

Julien.
