Hi,
The windows headers are almost the same. For instance winuser.h in wine
has more information than the Ming windows headers. I ran into problems
porting with Ming and went back to Wine.

Wine header winuser.h has this

/* defines below are for all win versions (_WIN32_WINNT >= 0x0400) ||
 *                                        (_WIN32_WINDOWS > 0x0400) */
#define SPI_GETMOUSEHOVERWIDTH    98
#define SPI_SETMOUSEHOVERWIDTH    99
#define SPI_GETMOUSEHOVERHEIGHT   100
#define SPI_SETMOUSEHOVERHEIGHT   101
#define SPI_GETMOUSEHOVERTIME     102
#define SPI_SETMOUSEHOVERTIME     103
#define SPI_GETWHEELSCROLLLINES   104
#define SPI_SETWHEELSCROLLLINES   105
#define SPI_GETMENUSHOWDELAY      106
#define SPI_SETMENUSHOWDELAY      107
 
#define SPI_GETSHOWIMEUI          110
#define SPI_SETSHOWIMEUI          111
 
/* defines below are for all win versions WINVER >= 0x0500 */
#define SPI_GETMOUSESPEED         112
#define SPI_SETMOUSESPEED         113
#define SPI_GETSCREENSAVERRUNNING 114
#define SPI_GETDESKWALLPAPER      115  

and Ming doesn't as I can see.

Here is a good example why we should take Caspers advice for having
wine header and wine dll code separate. See the following statements
make reference to NT ONLY.

SPI_GETMOUSEHOVERHEIGHT 
     Windows NT only: Gets the height, in pixels, of the rectangle
     within which the mouse pointer has to stay for TrackMouseEvent
     to generate a WM_MOUSEHOVER message. The height is returned in
     a UINT pointed to by the pvParam parameter. 

SPI_GETMOUSEHOVERTIME 
     Windows NT only: Gets the time, in milliseconds, that the mouse
     pointer has to stay in the hover rectangle for TrackMouseEvent
     to generate a WM_MOUSEHOVER message. The time is returned in a
     UINT pointed to by the pvParam parameter. 

SPI_GETMOUSEHOVERWIDTH 
     Windows NT only: Gets the width, in pixels, of the rectangle
     within which the mouse pointer has to stay for TrackMouseEvent
     to generate a WM_MOUSEHOVER message. The width is returned in
     a UINT pointed to by the pvParam parameter.

I need these three for porting comctl32.c to ROS.

FYI,
James
