  Use 0 instead of DDIR_READ to iterate from 0 to DDIR_RWDIR_CNT (2017-02-14 08:24:24 -0700)

----------------------------------------------------------------
Tomohiro Kusumi (6):
      configure: Drop default CONFIG_LITTLE_ENDIAN for Cygwin
      configure: Use x86 instead of i386 for $cpu for IA32
      Drop conditional declaration of disk_list
      Always set ->real_file_size to -1 when failed to get file size
      Add missing "rand"/"trimwrite" strings to corresponding ddir slots
      Use 0 instead of DDIR_READ to iterate from 0 to DDIR_RWDIR_CNT
