Isn't this a solution?

 

use of this define globally (such as make MYCFLAGS="-D_MSC_VER=1400" mingw) leads to a large number of errors at link time. and just have to do a patch, it is best to do so:

liolib.c:

 #if !defined(l_fseek) /* { */

  

- #if defined(LUA_USE_POSIX) /* { */

+ #if defined(LUA_USE_POSIX) || defined(__MINGW32__) /* { */

  

  #include <sys/types.h>

  

  #define l_fseek(f,o,w) fseeko(f,o,w)

  #define l_ftell(f) ftello(f)

  #define l_seeknum off_t

tested in MinGW 4.9.2 in Ubuntu and Windows (both x86_64 and i686 version).
