XftNameUnparse not found.

In the latest X.org builds, there is no XftNameUnparse function in libxft.
Many times (on ML's) is was said like "don't use it, it's going to be removed".

For now, I have openSUSE 10.2 and can't even compile the binary, as engine/playformX86UNIX/x86UNIXFont.cc uses this function.
In libXft 2.1.9 the XftNameUnparse is removed.

I think will be good to make some kind of workaround with this.
P.S. I'm not good in c++/linux to help in this case :(
