I wouldn't be so careless about sign conversion warnings. C can silently convert signed integers to unsigned and that can cause mayhem. I inherited a codebase that was exhibiting a classic signed conversion problem when a temperature reading dropped below 0°C. I simply turned on -Wextra and it flagged all the culprits with implicit conversion to unsigned. Throw in some casts and it was resolved.
