There're few more issues with this patch:
  - _chsize_s is not defined in headers (please make sure that your code 
compiles without warnings)
  - _chsize_s is not available in some versions of msvcrt.dll, you 
should load it using GetProcAddress like in other *_s functions tests
  - the tests are failing on windows, it's probably also caused by lack 
of _chsize_s header

Thanks,
Piotr
