That's a real shame because one of clang's greatest advantages over gcc
is it's warnings.  I've often wondered if there's some great warning
flags that could help me that I haven't turned on because I just don't
know about them. :(

Is there a -Wall-and-I-mean-really-all ?  If so, combined with -
fdiagnostics-show-option, one could start with everything and weed out
ones considered too noisy.
