As I recall, this warning was implemented because, in a previous 
release, placing the bibliography command before any other commands 
caused a segmentation fault.  The behavior was fixed: no segfault, but 
when these commands are out of order, no output is produced, which was 
presumably not the intended result - hence the warning.
