Gtk -- trying to run pixmap example

["ringo" <ringo margaritasrus com>]

I downloaded gdk 2.0 and unzipped it. I've been compiling and looking at
the examples. I just tried to compile the pixmap example and I get an
error: config.h: No such file...
In the main directory that was created when I unzipped I see config.h.in
and config.h.win32, but no config.h . What do I need to do to fix this?
Thanks
Ringo
