If you're using GTK 2.0, which it looks like you should be, then the
command to compile would be:

$ gcc -o gtk-thread gtk-thread.c `pkg-config --cflags --libs gtk+-2.0`

Hmm, the mixing of GTK+ 1.2 and 2.0 is probably causing this problem.
Try using one or the other, but not both (in other words, gtk-config
if you're using 1.2, or pkg-config if you're using 2.0).
