Logging UnitTest failed on x64 VS2015. Reason: Pointer format not consistent

[flm8620]

In logging_unittest.cc, we try to log a void* p = reinterpret_cast<void*>(0x12345678); in RAW_LOG(INFO, "ptr %p", p); format.
The golden file logging_unittest.err contains also a IDATE TIME__ THREADID logging_unittest.cc:LINE] RAW: ptr 0x12345678
When I build on x64 mode, outputs are:

Golden file string:

...
IDATE TIME__ THREADID logging_unittest.cc:LINE] RAW: ptr 12345678
...

Test generated string:

...
IDATE TIME__ THREADID logging_unittest.cc:LINE] RAW: ptr 0000000012345678
...

Which causes a fail.

By the way, diff command doesn't exist under Windows. Maybe test also for FC command, which gives a better experience for MSVC users.
