Sorry, that was not clear to me from you message.

Try latex --help

When latex was run by tex and pdflatex by pdftex (some years ago),  
you cloud check for the existence of \pdfoutput (\ifx\pdfoutput 
\undefined etc.). Code that uses this is now broken, and should be  
replaced by the ifpdf package, which conducts the proper check. I  
don't recall if the now broken trick was contained in some TeXShop
