const-char

So I'm working on an exceedingly large codebase, and recently upgraded to gcc 4.3, which now triggers this warning:

warning: deprecated conversion from string constant to ‘char*’

Obviously, the correct way to fix this is to find every declaration like char *s = "constant string"; or function call like void foo(char *s); foo("constant string"); and make them const char pointers. However, that would mean touching 564 files, minimum, which is not a task I wish to perform at this point in time. The problem right now is that I'm running with -werror, so I need some way to stifle these warnings. How can I do that?
