B.12 old_function Eliminated

PHP/FI had a quirky function declaration syntax:

 function sum $a, $b (     return($a + $b); ); 

This was changed in PHP 3, but you could continue to use the old form in PHP 3 and PHP 4 if you declared your function as an old_function :

 old_function sum $a, $b (     return($a + $b); ); 

Alas, after six years , this backward compatibility feature is now gone. Another nostalgic remnant of PHP/FI has passed away.
