+It is recommended that one builds the dependencies with VS9 as far as
+possible, especially those from and using the GTK+ stack (i.e. GLib,
+ATK, Pango, GDK-Pixbuf), so that crashes caused by mixing calls
+to different CRTs can be kept at a minimum.  zlib, libpng, and Cairo
+do contain support for compiling under VS9 using VS
+project files and/or makefiles at this time of writing, For the
+GTK+ stack, VS9 project files are either available under
+$(srcroot)/build/vs9 in the case of GLib (stable/unstable), ATK
+(unstable) and GDK-Pixbuf (unstable), and should be in the next
+unstable version of Pango.  There is no known official VS9 build
+support for fontconfig (along with freetype and expat) and
+gettext-runtime, so please use the binaries from:

+*About the dependencies marked with *: I will see whether it is possible

+ building and running GTK+ itself, but note that they are needed for
+ people running and building GIMP. They are referred to by components
