[Xlibs] Where is libXt?

[Jeremy C. Reed]

I have now built and installed xproto, xextensions, xtrans, libXau and
libX11.

I now want to build xpm (http://www.inria.fr/koala/lehors/xpm.html). It
uses libXt, such as
X11/StringDefs.h
X11/Intrinsic.h
X11/IntrinsicP.h
X11/Shell.h

Is the Xfree86 version of xc/lib/Xt available as a separate project?

I didn't see at http://www.freedesktop.org/Software/xlibs but I may have
missed it.

Thank you,
