Except that shuts it up for short, int and long as well.

char is weird in that it has _three_ different signednesses: signed, unsigned, 
and just plain "char" which varies from platform to platform.  In my projects 
I feed in something like -funsigned-char (which I prefer over -fsigned-char 
because being 8 bit clean makes things like utf-8 easier).  Things like 
strcat never actually char about the signedness of the characters, and yet 
we're forced to care when doing string manipulations by stupid compiler 
warnings...
