  64     This structure differs from the Win95 original,
  65     but this should not matter since it is strictly internal to
  66     the thunk handling routines in KRNL386 / KERNEL32.
  67
  68     For reference, here is the Win95 layout:
  69
  70     struct ThunkDataCommon common;            /* 00 */
  71     DWORD                  flags1;            /* 08 */
  72     SEGPTR                 apiDatabase;       /* 0C */
  73     WORD                   exePtr;            /* 10 */
  74     WORD                   segMBA;            /* 12 */
  75     DWORD                  lenMBATotal;       /* 14 */
  76     DWORD                  lenMBAUsed;        /* 18 */
  77     DWORD                  flags2;            /* 1C */
  78     char                   pszDll16[256];     /* 20 */
  79     char                   pszDll32[256];     /*120 */
  80
  81     We do it differently since all our thunk handling is done
  82     by 32-bit code. Therefore we do not need do provide
  83     easy access to this data, especially the process target
  84     table database, for 16-bit code.
