+This file describes how to make a threaded X11R6.
+
+You need the source-code of XFree-3.2. I used the sources of X11R6.1
+(files: xc-1.tar.gz xc-2.tar.gz xc-3.tar.gz) and the patches to
+XFree-3.2 (files: README.X11.patch R6.1pl1-3.2.diff.gz cfont32.tgz).
+
+Untar the xc-?.tar.gz files in a directory called XF3.2 and apply
+the XFree-3.2 patches as described in README.X11.patch or use the
+whole XFree86 source.
+
+Now apply the thread patch with
+
+patch -p0 < XF3.2.xc.diff
+
+Go to the XF3.2/xc directory and make the whole thing:
+nice make World >& world.log &
+tail -f world.log
+
+Wait a few hours or interrupt the process after the shared libs
+are made. The shared libs are:
+
+XF3.2/xc/lib/ICE/libICE.so.6.0*
+XF3.2/xc/lib/PEX5/libPEX5.so.6.0*
+XF3.2/xc/lib/SM/libSM.so.6.0*
+XF3.2/xc/lib/X11/libX11.so.6.1*
+XF3.2/xc/lib/XIE/libXIE.so.6.0*
+XF3.2/xc/lib/XThrStub/libXThrStub.so.6.0*
+XF3.2/xc/lib/Xaw/libXaw.so.6.1*
+XF3.2/xc/lib/Xext/libXext.so.6.1*
+XF3.2/xc/lib/Xi/libXi.so.6.0*
+XF3.2/xc/lib/Xmu/libXmu.so.6.0*
+XF3.2/xc/lib/Xt/libXt.so.6.0*
+XF3.2/xc/lib/Xtst/libXtst.so.6.1*
+
+(The Program dga didn't compile, but I have not check out why.)
+
+Now you can copy the resulting libs   
+
+cp XF3.2/xc/lib/*/*.so.?.? /usr/X11R6/lib/
+
+and create some links
+
+cd /usr/X11R6/lib/
+ln -s libXThrStub.so.6.0 libXThrStub.so.6
+ln -s libXThrStub.so.6 libXThrStub.so
+
+or use make install (not tested, and needs new configuration).
+
+It is possible with the libXThrSub to compile X11 programs without linking
+libpthread to them and not necessary to recompile already installed
+unthreaded X11 programs, because libXThrSub keeps the dynamic linker quit.
+On the other hand you can link libpthread to a X11 program to use threads.
+
+I used linux 2.0.23 and libc 5.4.7 .
