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