Bug#344919: teTeX 3.x incompatible to older .sty files

[Tilman Höner zu Siederdissen <tilman.hzs@web.de>]

Yes, I can guess which decision was made. :)
I will try get the OSA to change their style file. That might save some 
scientists who use teTeX a lot of trouble.
But, since it's an important issue, I suggest to mention this in the 
documentation or the FAQ. Something like the following would have been 
very helpful to me when I encountered this problem:
Q: I chose dvi mode but only a pdf was created. What's wrong?
A: Some style files use a wrong test to determine whether pdf or dvi is 
to be created. Look for "\pdfoutput" in your style files. ... [the rest 
could be taken from the explanation here:
