        <pre>Hello

compilation of cairo fails with opam switch 4.03.0+flambda.
Cairo/autoconf looks for lablgtk2 directory, which is in my case
/home/src/Ocaml/opam-ocaml-4.03.0/4.03.0+flambda/lib/lablgtk2/.
The problem seems to be the "+" (that comes from opam switch name), which seems
to be translated to some other standard path name :

ocamlc.opt -ccopt "-g -pthread -I/usr/include/gtk-2.0
-I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/gio-unix-2.0/
-I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/cairo
-I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12
-I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng12 -I/usr/include/glib-2.0
-I/usr/lib/x86_64-linux-gnu/glib-2.0/include
-I/home/src/Ocaml/opam-ocaml-4.03.0/4.03.0/home/src/Ocaml/opam-ocaml-4.03.0/4.03.0+flambda/lib/ocaml/flambda/lib/lablgtk2/"
