      Description

      If I build the cpp library with MSVC for windows and try to use the hdfs io interface, the dynamic library loads fail.

      The reason is that in file hdfs-internal.cc on two occasions the __WIN32 define is checked instead of _WIN32. The former is not set by MSVC. I checked that these are the only two locations in the arrow library where the flag __WIN32 is used, so all we need to do is replace these two references in hdfs-internal.cc.
