cc_proto_library rules fail to link on Windows with bazel 0.7.0

See original GitHub issue

Description of the problem / feature request / question:

With bazel 0.6.1 cc_proto_library rules build, but with 0.7.0 the rules fail to link. This happens regardless of whether the MSVC wrapper is used. I don’t see any .so outputs from the 0.6.1 build, but 0.7.0 fails when linking .so files.

If possible, provide a minimal example to reproduce the problem:

In an empty directory on Windows:

WORKSPACE

local_repository(
    name = "com_google_protobuf",
    path = "protobuf",
)
local_repository(
    name = "com_google_protobuf_cc",
    path = "protobuf",
)
bind(
    name = "protobuf",
    actual = "@com_google_protobuf//:protobuf",
)
bind(
    name = "protoc",
    actual = "@com_google_protobuf//:protoc",
)

BUILD

cc_proto_library(
    name = "my_cc_proto",
    deps = [":my_proto"],
)

proto_library(
    name = "my_proto",
    srcs = ["my.proto"],
)

my.proto

syntax = "proto2";

message msg {
  optional int32 val = 1;
}

git clone https://github.com/google/protobuf bazel build :my_cc_proto

Environment info

Operating System: Windows 10
Bazel version (output of bazel info release): 0.7.0

Have you found anything relevant by searching the web?

I posted in bazel-discuss, @laszlocsomor asked for repro

Anything else, information or logs or outputs that would be helpful?

Some of the errors:
