THREADINFO Compatibility Flags

The THREADINFO, CLIENTINFO and, in version 4.0, the PROCESSINFO structures share a set of bit flags as their dwCompatFlags member. Type information in symbol files for WIN32K.SYS in Windows 7 (only) enumerates the defined flags as UINT bit fields for their appearance in the THREADINFO.

It seems unlikely that I shall ever attempt an enumeration of which flags are defined in which versions, but you never know.

The misspelling DealyHwndShakeChk is Microsoft’s.
