How to compile examples against gtk-1.3.7

[Sandy Xu <sandyfox sina com>]

Hi, 
  I'm a new gtk+ user and this is a simple question. I just don't know
how to compile my examples against the gtk+2.0(actually 1.3.7 in my
RH7.1 box). I use gtk-config --cflags and --libs, but it produces still
gtk+1.2 things. How can I do? Is it something related with the --prefix
options?    
  Sorry to bother you. Obviously this is a duplicate question. But I can
not find it in the archives. Please cc me(I'm not on this list).
