You want the programmer to type the word literally?
And how will typing the word literally all the time answer that question?

I think a better warning would be the factual one along the lines that
root and "\\", being statically addressed evaluate to a constant expression  
which branches only one way. Something like:

warning: conditional is constant

It would also apply to things like: if(1) {}

But not to things like astring == bstring which makes sense to compare two  
variable string pointers. Personally, I leave all sorts of warnings in my  
code just to remind me of some sensitive cross-platform issues with our code.  
I wouldn't want to be asked a question by the compiler the 1000 times a day  
I recompile (if that is what you mean). This is the first time I read this  
thread so I can be way of base...
