Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

The following build file does not compile under windows

cc_library(
    name = "long",
    includes = ["a" * 32768]
)
cc_binary(
    name = "long_bin",
    srcs = ["main.cpp"],
    deps = [
        ":long"
    ]
)

The reported error is
Action failed to execute: java.io.IOException: ERROR: src/main/native/windows/processes-jni.cc(161): CreateProcessWithExplicitHandles("C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\cl.exe" /c main.cpp /Fobazel-out/x64_windows-fastbuild/bin/_objs/long_bin/main.o /nologo /DCOMPILER_MSVC /DNOMINMAX /D_WIN32_WINNT=0x0(...)): command is longer than CreateProcessW's limit (32768 characters)

From what I could tell when trying to make a simple repo it appears this case may be handled correctly for link steps but not for compile steps.
