There was no circular dependency for glib-1.2.10. In fact when I ported
it I had never heard of pkg-config. Anyway, I have built
pkgconfig-0.12.0, with your patch, and gnome-vfs configure works fine
with it. So if/when it is adopted as the "official" cygwin version I
will remove pkg-config from my website.
