I don't have the standard on hand.  The problem I had was the following.

If you used k&r definitions the compiler assumed arguments where passed
as ints unless larger.  The same compilers in other files using the
prototypes would pass arguments smaller than integers if possible.

Perhaps thats just a problem with __P() in general. If so then I change
my reason for not using it to the above. :)
