That will break every time glibc changes in a way that causes warnings.
e.g., the "macro strcmp used without args" ones aren't reasonably fixable;
when glibc 2.2 changed the iconv prototype, that caused warnings; glibc
2.2.1 causes the "ISO C99 requires rest arguments to be used" warnings
every place printf is used with just one argument.
