Library for GUI?

gui

#21

To check I just compiled it with 4.05.0+flambda and everything just worked. Including examples.

True, that I have another change in Makefile which changes the target distclean and configure (do no rememember, why I needed them)

--- a/Makefile
+++ b/Makefile
-distclean: clean ocp-distclean
+distclean: clean
+	rm -rf config/autom4te.cache config/config.status config/config.log
+	rm -f config.ocp config/Makefile
 	rm -f ocp-build.root*
 
+configure: config/configure.ac config/m4/*
+	cd config; \
+		aclocal -I m4; \
+		autoconf
+
