That's weird.
Can you tell the version of MinGW-w64 you are using and where you 
downloaded it from?

I did test with with MinGW-w64 and the Large File Support workaround, 
that is added with the defines above, and that relies on redefining 
off_t to off64_t as is the case on other platforms, should not prevent 
the off64_t to be properly defined from stdio.h

In the MinGW-w64 I use (from TDM-GCC), stdio.h defines the offeset types 
as follows:

#ifndef _OFF_T_DEFINED
#define _OFF_T_DEFINED
#ifndef _OFF_T_
#define _OFF_T_
  typedef long _off_t;
#if !defined(NO_OLDNAMES) || defined(_POSIX)
  typedef long off_t;
#endif
#endif
#endif

#ifndef _OFF64_T_DEFINED
#define _OFF64_T_DEFINED
  __MINGW_EXTENSION typedef long long _off64_t;
#if !defined(NO_OLDNAMES) || defined(_POSIX)
  __MINGW_EXTENSION typedef long long off64_t;
#endif
#endif

Thus, none of what we do should have an impact on off64_t and _off64_t 
being accessible. But apparently, that is not the case on your platform.

Can you please have a look at your stdio.h and let me know how off64_t 
is defined there (if defined at all)?
