Extended Description

Summary says it all. I expected that some phase or another of sac2c would
remove the dead variable "junk" from the function prototype and call of foo.
However, this does not seem to be the case.
use Array: all;
use StdIO: all;
int[*] id(int[*] x)
{ return(x);
}
int[*] foo (int[*]x, int[*] junk2)
{
 return(x*10);
}
int main()
{
 junk = id(23);
 x = iota(id(55));
 z = foo(x,junk);
 print(z);
 return(1);
}
