+> I have noticed 2 issues when trying to use iowin32 functions for a
+> desktop (not Win RT) program.
+>
+> 1) IOWIN32_USING_WINRT_API is always defined.
+>
+> The WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP) test always evaluates
+> to true so WINRT APIs (CreateFile2, SetFilePointerEx) always get used.
+> There are 2 solutions:
+> - Use WINAPI_FAMILY_ONE_PARTITION(WINAPI_FAMILY, WINAPI_PARTITION_APP).
+> The comments in the Include/shared/winapifamily.h file in the Windows
+> Kit show that this is the test to include RT apps but exclude desktop.
+> - Add a test to ensure that _WIN32_WINNT >= 0x0602.
+> I have opted for the first solution in my attached patch.
+>
+> 2) dwMoveMethod is not propagated to SetFilePointer.
+>
+> The dwMoveMethod flag is correctly passed to SetFilePointerEx but not to
+> MySetFilePointerEx & SetFilePointer. It is always FILE_CURRENT.
+> As a result, it is impossible to unzip a file when not using Win RT APIs.
