As the compiler documentation states, warn_unused_result was intended
for cases where failing to check the return value is always a security
risk or a bug.  The documentation cites the example of realloc.  That
is a case where casting the return value to (void) would always be
wrong.  The compiler really should warn for that code by default; if
you have some crazy need to ignore the result of realloc, just use the
-Wno-unused-result option.

Still getting the warning.
