[LCP]Porting code from K&R -> ANSI

I'm afraid that not really.
The compiler will issue an error if it can detect this, but as soon
as you pass a pointer to the string around, it can't tell if it
points to a string constant or not, so you'll have to dig yourself.
Another possibility (not practical at all though) is to add const
correctness to your code, and that is going to be an awful experience
if you use K&R code :)
