Please describe the problem:
Some 64bit compilation cleanups.  Detailed & patched in Gentoo here:
http://bugs.gentoo.org/show_bug.cgi?id=124167

The following warnings were encountered while building on an amd64:

/var/tmp/portage/gnucash-1.8.11/work/gnucash-1.8.11/src/gnome-utils/dialog-account.c
        dialog-account.c:1328: warning: cast to pointer from integer of
different size
        Fixed

        window-acct-tree.c:98: warning: cast to pointer from integer of
different size
        This isn't really an error but just the way callbacks & functions as
parameters work with gtk.  :/
