I think setjmp and longjmp should be treated as a warning, and replaced with sigsetjmp and siglongjmp, but not a fatal error, if I recall correctly, grub has its own setjmp/longjmp implementation. Probably should be a rpmlint warning, like the one of libraries that call exit. > Andy Paulo -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
