No, but I will add one.
Modulo using a unique name for the .c file or doing it in
its own subdir, I guess it'd be something like this:
(but maybe using $CC instead of gcc)
(gcc -v) > /dev/null 2>&1 ||
{ echo '$0: this test requires gcc; skipping' 1>&2; exit 77; }
cat <<\EOF > in.c
#include "ignore-value.h"
int f (void) __attribute__ ((__warn_unused_result__));
void g (void);
void g (void) { ignore_value (f ()); }
EOF
exec gcc -Werror -c in.c
