If the warning indicates a real issue in the code, suppressing the warning merely masks the problem. If not, then there's the issue of not being able to suppress the warning, as with GCC, or the additional line noise in the form of preprocessor directives or pragmas.

I don't want problems hidden and I'd prefer that the code not have any more preprocessor/pragma line noise than required. Even if I'm not the maintainer, I know that reducing that line noise means that future changes will be easier for the maintainer.
