I don't follow.  What exactly is annoying?  Please explain.

Nope.  FreeType uses exactly the same code on both platforms, and it
never converts fonts on the fly.

Certainly not.  This is not a FreeType problem, since kerning and the
like is handled one level above FreeType.  I've specifically added
Behdad's reply to the tracker who is willing to help the issue.
However, this needs someone using the Windows platform and the ability
to compile code...
