Keep a list of current GtkRcFiles being parsed, not just the directories

Thu Aug 21 16:00:36 2003  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkrc.c: Keep a list of current GtkRcFiles
        being parsed, not just the directories for those
        files. Use that to catch recursion. (Part of
        #114988)
