Scren capture showing Split Buttons working on Windows 7

I have just been updating SIV (http://rh-software.com/) to use Split Buttons
(http://msdn.microsoft.com/en-us/library/aa511453.aspx) on Windows Vista and
later systems.  When I tested on Wine 1.1.29, after setting the Windows Version
to Vista, all of my calls DialogBoxIndirectParam() calls started failing and I
guessed was down to Wine not supporting these.  I then searched the source for
BS_SPLITBUTTON and BS_DEFSPLITBUTTON neither of which are defined which I feel
confirms this.

Please can the addition of Split Button support be added to the list of planned
enhancements.

I have currently worked around this by not using then on Wine, even when it
announces itself as Windows Vista.  I have also added a -SPLIT command line
qualifier to force their use and am happy to made a SIV 4.02 Beta release
available for testing should support be added before I actually release 4.02.
