Kinda interesting to note that C=2 does'nt list all potential gcc  
warnings :( if one wanted a collated list of all warnings, rm .../*.o  
helps I guess.

C=2 only runs sparse - so if you're committing patches to fix sparse
warnings, that's what you should be interested in.

I'd suggest that fixing sparse warnings and GCC warnings in a single
patch is probably not the best thing to do - GCC warnings are less
subjective than sparse warnings.
