This is indeed a more complete check for pdftex / pdf
output, and I did something similar at first.  The reason I
did not leave it this way was because when \pdfoutput=0, I
would first print a warning, and then later pdftex would
issue its own error message at the first instance of
\pdfstartlink / \pdfdest; my warning seemed excessive to me.

Or maybe I was wrong?  The user might not even know what
\pdfstartlink / \pdfdest is.  Maybe it is better to print a
more user-friendly warning before pdftex bails out with its
own (possibly confusing for the user) error message?  If
this seems more appropriate I can send the updated patch (or
maybe Karl could make the change himself, to avoid extra
traffic on the list).

Thanks for watching out for my boo-boos.  There should be
some :)
