/* In Linux the `stat' call is actually done by emulating a `xstat' system
   call, which takes an additional first argument giving a version number
   for `struct stat'.  Likewise for `fstat' and `lstat' there are `fxstat'
   and `lxstat' emulations.  This macro gives the Linux version number that
   corresponds to the definition of `struct stat' in <statbuf.h>.  */
