Not all compilers produced after 1999 conform to the C99 or
C11 standard, and a non-fatal warning satisfies the standard's
requirement for a diagnostic.  Many compilers have an option to make
such diagnostics fatal.  If a warning isn't good enough for you,
find out how to make the error fatal.  Use a different compiler
if necessary.  If a compiler claims to conform to C99 and doesn't
issue at least a warning, submit a bug report -- to the compiler
provider, not to comp.lang.c.
