That's really strange.  Convince yourself #include <glib.h>
is on line 29 of gdk-pixbuf/gdk-pixbuf.h and therefore it
is included before it gets to line 33.  If you included
<glib.h> (not "glib.h") I don't understand how it could find
a different glib.h.

I don't know what Slackware does with GLib, but my theory is
you have more than GLib installed.  What locate glib.h,
locate gtk.h finds?

These two are consistent.  But unless Slackware mangles Gtk+
beyond recognition, there is no G_GNUC_NULL_TERMINATED in
Gtk+ 2.6.3, nor in any other 2.6.x version.  So the header
files your app tried to include belong to another instance
of Gtk+.

Try pkg-config --variable=prefix libfoo to find out where
the libfoo found by pkg-config is located.

If gtk-2-2.4.3 is what you expect to have installed this
supports the theory you have a pell-mell, not a particular
version.

GLib, Gtk+, Pango, etc. version numbers are unrelated (Gtk+
and GLib versions used to be related, but it is no longer
true).  What version of what is required is probably written
in some docs, I would run or look at configure.{ac,in} of
each library in question.

Do not install anything to /usr/local.  You could end up
with three+ versions installed simultaneously and even in
the best case you will still have two versions installed.
The files can be easily compared without actually installing
them.

What you need is not installation of another version, but
location and identification of everything you have already
installed and *removal* of the extra/unneeded libs.
