Compilation warnings with gcc 4.2 => script to automate fix ?

Hi all.

No a big pb ;-), but one day or another, it will be a compilation error :
nearly everywhere in torcs code, my gcc 4.2.2 issues the following warning :

Warning : deprecated conversion from string constant to 'char*'

Has anyone already fixed this future pb ?

If not, may I suggest to change nearly everywhere the way strings are passed
as parameters from "char *" to "const char *" ?
Of course, I'm conscious that its would change nearly every source file in 
Torcs, so I propose to try and build a script to automatically
and intelligently make the changes (if possible) ; that way, we would be free to 
simply test it home, and then one day decide when we want that massive commit 
(right before a release ?).

Thanks for you input.

Jean-Philippe.
