My kernel certainly compiles.

I checked that every single filesystem can be compiled with the flag.

But yes, the fact that _I_ am anal about not having warnings does not
mean that everybody else is. I added -Werror to see if people would fix
some of the things it shows, and I've already gotten some patches. More
are certainly needed.

I'll probably end up dropping -Werror at some point before the real
2.4.0, if for no other reason than the fact that there are lots of gcc
versions out there that complain about bogus things (the signed/unsigned
comparison warnings in some gcc versions are basically not possible to
fix, which is why no "real" gcc version does this warning by default to
my knowledge). 

And anybody who isn't interested in fixing them might as well remove the
-Werror from their makefile too.

But maybe it will cause some cleanup.
