calling *W functions in wt (Was: dlls/shell32/shfldr_desktop.c)

[Saulius Krasuckas]

Hello Ge and especially unicoders: 
Alexandre, Dimi, Dmitry, Rob, Shachar, Troy and others.

I am not sure of how should be file operations implemented in winetest:

*FileW and *DirectoryW functions fail on every win9x box as they are 
unimplemented here. They succeed only when app is linked to MS Layer for 
Unicode (MSLU) and MSLU is installed. [1]

I was trying to replace every failing unicode function with its ascii 
counterpart in one of the wt files [2], but that looked ugly to me.

Maybe it would be really nice and possible to link wt to unicows.lib on 
windows.  In this case we need a corresponding static lib in Wine too, 
right?  It probably will be "empty" because UNICOWS.DLL shouldn't be 
loaded as Wine doesn't lack implementation of mentioned functions.  
Though, I have no guess if this could be done easily.

What could be a clean and acceptable solution?  Your comments, please.
