That site does not seem to be available at the moment, but the issue
seems simple enough: the GTK people really don't want you to include
specific headers aside from gtk.h. If I remove the include for
gtkscrolledwindow.h, everything compiles fine.

For the record: this is on Debian 7 (Wheezy), which has libgtk3
3.4.2. The header gtkscrolledwindow.h has this as the top:

  #if !defined (__GTK_H_INSIDE__) && !defined (GTK_COMPILATION)
  #error "Only <gtk/gtk.h> can be included directly."
  #endif
