Can you help me compile a single widget?(I want to patch it later on).

Hi, I want to use GtkFixed as my preferred container(yes I am aware of the warnings against it). Currently there is an old bug that prevents me from fully utilising it. I am referring to bug 81630. Although there are available 2 patches there is no word from the developers. I want to test them myself. If they work I just want to use the patched GtkFixed and NOT compile the whole Gtk+ and link it with my small application. I figured that all I had to do was just change GTK_FIXED*/gtk_fixed* to GTK_FIXED2*/gtk_fixed2*. But before that I wanted to test if I can compile GtkFixed alone(using the original code). The result was dissapointing. Anyways, a quick run on what I did. I grabbed the gtk-2.18.3 source(this is used by my distro). I grabbed gtkfixed.c and gtkfixed.h and put them on a separate folder. There I created a test.c which included gtkfixed.h and a dummy main(). (to make gcc happy). Then I tried to compile with "gcc test.c gtkfixed.c -o test `pkg-config gtk+-2.0 --libs --cflags`". This resulted in errors for missing headers. So I grabbed and put in the same folder gtkprivate.h, gtkintl.h, gtkalias.h and gtkaliasdef.c. After that it still complained about "config.h" so I just run "./configure" on the gtk2.18.3 source and then grabbed the resulting config.h. After that it compiles about things I cannot understand and solve. The first few lines are:

/tmp/cc7diEaF.o: In function `gtk_fixed_get_type':
gtkfixed.c:(.text+0x8f): undefined reference to `IA__gtk_container_get_type'
/tmp/cc7diEaF.o: In function `gtk_fixed_class_init':
gtkfixed.c:(.text+0x1da): undefined reference to `IA__gtk_container_class_install_child_property'
gtkfixed.c:(.text+0x237): undefined reference to `IA__gtk_container_class_install_child_property'
/tmp/cc7diEaF.o: In function `gtk_fixed_child_type':
gtkfixed.c:(.text+0x24f): undefined reference to `IA__gtk_widget_get_type'
/tmp/cc7diEaF.o: In function `gtk_fixed_init':
gtkfixed.c:(.text+0x262): undefined reference to `IA__gtk_object_get_type'

Can you help me with this? Is my approach correct? If not, can someone guide me through? I really want to solve this(get a working patched gtkfixed).
