After discussion with David Turner at freetype-devel, I feel confident
this issue is resolved.

Since the issue was already raised at
https://bugs.freedesktop.org/show_bug.cgi?id=603, I have placed the
patch there. It includes xorg/configure.ac code for switching on
freetype support, only when XPRINT is switched on (can be disabled with
--disable-freetype).

In the course of testing, I found a bug in lib/Xfont: BUILD_FREETYPE was
still being used instead of XFONT_FREETYPE.

Could I kindly request you to apply both patches (attached to bug #603)?
This will enable #603 to be closed.


The other two matters still need resolution:

Until these latter two problems are fixed, Xprt will not build.  In the
meantime, the patches described above will not cause problems building
the basic Xprt server if --disable-freetype is used in the Xprint
autogen line.
