It took me some time to figure out that "Other_Libs" is not a predefined
variable. But grepping through the gcc-CVS showed it ;)

And the line is "Default_Switches", not Default_Options. I managed
to build the application with the following settings:

   package Linker is
      for Default_Switches ("Ada") use
         ("--static",
          "/usr/lib/libgtkada2.a",
          "/usr/lib/libgtk-x11-2.0.a",
          "/usr/lib/libgdk-x11-2.0.a",
          "/usr/lib/libatk-1.0.a",
          "/usr/lib/libgdk_pixbuf-2.0.a",
          "/usr/lib/libm.a",

          "/usr/lib/libpangoxft-1.0.a",
          "/usr/lib/libpangox-1.0.a",
          "/usr/lib/libpango-1.0.a",
          "/usr/lib/libpangoft2-1.0.a",

          "/usr/lib/libgobject-2.0.a",
          "/usr/lib/libgmodule-2.0.a",
          "/usr/lib/libglib-2.0.a",
          "/usr/lib/libdl.a",
          "/usr/X11R6/lib/libXrandr.a",
          "/usr/X11R6/lib/libXi.a",
          "/usr/X11R6/lib/libXext.a",
          "/usr/lib/libXft.a",
          "/usr/lib/libfontconfig.a",
          "/usr/lib/libpthread.a",
          "/usr/lib/libc.a",
          "/usr/lib/libjpeg.a",
          "/usr/lib/libtiff.a",
          "/usr/lib/libpng.a",
          "/usr/lib/libz.a",
          "/usr/lib/libfreetype.a",
          "/usr/lib/libXcursor.a",
          "/usr/lib/libXrender.a",
          "/usr/X11R6/lib/libXinerama.a",
          "/usr/X11R6/lib/libX11.a",
          "/usr/lib/libexpat.a");

   end Linker;

And there are other things I didn't know: it's not sufficient to
include all the static libraries it's also important in which *order*
you mention them. This order above works, if you move some of
the libs below (let's say libz) to the beginning of the list the
linking process fails. Until now I don't know why. Someone else?

Unfortunately it also requires libs which are neither directly
nor indirectly mentioned in the .so-versions. Ok, I might have
missed some libs but ldd to the so-libs never gave me libtiff
or libpng.

My executable is <9MB, that's ok (the machine has 1GB RAM). ;)
