--- Comment #73 from Zdenek Sojka <zsojka at seznam dot cz> --- See MISRA C:2012 Rule 17.7: "... If the return value of a function is intended not to be used explicitly, it should be cast to the void type. ..." It would be helpful if gcc could be used to write MISRA-compliant code, or at least if it wouldn't generate compilation warnings when the programmer is targeting MISRA-compliancy. I understand this might be a very complex topic, due to gcc being free software, and other companies possibly providing / selling the tool qualification.
