• Avoid using ssize_t (a28b439)
• Avoid using *nix only headers when using libuv (a469f4d)

Unresolved issues

1. Examples can't be built

Looks like there's an issue with protobuf (or cmake configs) where it's failing to find protoc?

ninja: error: 'examples/errors/proto/protobuf::protoc', needed by 'examples/errors/proto/examples/v1/errors.grpcxx.pb.h', missing and no known rule to make it

2. Error C2894 when building with libuv
