mmsystem16.h incorrect? SEGPTR vs. LPSTR

[Joerg-Cyril.Hoehle at t-systems.com]

Alexandre, Damjan, Eric,

I understand your answers mean that a patch is needed to MCI_*_PARMS16 in mmsystem16.h to turn all occurrences of LPSTR into SEGPTR.  E.g. MCI_LOAD_PARMS16, MCI_DGV_INFO_PARMS16, MCI_DGV_OPEN_PARMS16 ...

I suppose "DWORD dwCallback;" is ok to copy 1:1 (what the code currently does)
because it contains a window handle, not pointer.
It would be wrong if the 16bit SDK contained
     HWND16  wCallback;
     UINT16  wReserved0;
because then Wine might see half garbage and be lucky when wReserved is 0.
