cannot build gtk_-2.0.9

[George Strauss <george gnome org>]

Hi,
I hope someone can help. I am trying to build gtk+-2.0.9 without libpng, 
libjpeg and libtiff.
It configures but refuses to build. The following error message is 
generated.

I do not know if I am doing something wrong or if the --without-libpng 
configure option is meaningless.  Any help is greatly appreciated. 
Thanks in advance.
