The update looks good and the gtest passed. I saw the following in the 
test log:

[----------] 2 tests from os_windows
[ RUN      ] os_windows.reserve_memory_special_test_vm
[       OK ] os_windows.reserve_memory_special_test_vm (0 ms)
[ RUN      ] os_windows.handle_long_paths_test_vm
Disabled UNC path test, since T: is not mapped as share T$.
[       OK ] os_windows.handle_long_paths_test_vm (13835 ms)
[----------] 2 tests from os_windows (13835 ms total)

thanks,

Calvin
