I presume you're system is x86_64? I asked the same question in July:

http://mail.gnome.org/archives/gtk-app-devel-list/2007-July/msg00038.html

The executive summary for the thread is that it's an incorrect cast in
GLib that only affects x86_64 with optimizations turned on. Likely
you'll have to live with or disable the warnings until 64-bit systems
become common enough that this bites someone with the wherewithall to
track down the proper source of the problem in GLib.
