Hello,

could you give a little more information please? In particular, does "Cal" 
work with older versions of gcc? Does "J" still work or is it rejected 
with a recent gcc? Do they mean the same thing?

I trust that you know what you are doing, I just like to understand a 
patch before applying it.
