Yes, they do.
gtk.h includes gdk/gdk.h. --> gtk+-2.0.pc Requires: gdk-${target}-2.0
gtkwidget.h includes atk/atkobject.h --> gtk+-2.0.pc Requires: atk
gdkx.h includes X11/Xlib.h --> gdk-x11-2.0.pc needs Requires: x11
etc. ad nauseam, grep is your friend. ;-)
I tend to think the Requires on cairo should not be there. (Not that
it makes any difference gdk-x11-2.0.pc rightfully requies it.)
The -lm is caused by brokenness in gdk-pixbuf-2.0.pc
(just Libs: instead of splitting into Libs: and Libs.private)

gnutls is not in the same boat as gtk*. None of gnutls headers include
headers from tasn. Requires are not necessary for gnutls.
