All our glyphs come from freetype directly. So it is the freetype 
library that makes that decision.

A quick search on freetype and cleartype shows this

Looks like it is a big patent mess.

But in short I do not think this is a wine issue but more a freetype 
issue.  It looks like there are special parameters that could be passed 
to FT_Open_Face to force hinting (looking at the freetype release 
notes).  But that would require a bit more investigation if you are 
interested. And then you would have to prove when windows does this.
