It would be nice if the warning "comparison is always true due to limited range
of data type" could be turned off. From looking at the gcc source I conclude it
can't. I couldn't find a workaround which generates the same code (casting the
smaller type to the wider type just for the comparison doesn't silence the
warning, using a wider type for the variable generates worse code).
Yet better if it could be turned off locally. I know which comparisons in my C
macro may trigger it, and it would make sense to turn it off only in these
places.
