The location could be better but it is pretty close for C++:
test.c:4:14: warning: right operand of comma operator has no effect
[-Wunused-value]
(void) x, y; /* warning: right operand of comma operator has no effect
^
But the C FE is pretty awful:
test.c:4:3: warning: statement with no effect [-Wunused-value]
(void) x, y; /* warning: right operand of comma operator has no effect
^
Clang:
test.c:4:13: warning: expression result unused [-Wunused-value]
(void) x, y; /* warning: right operand of comma operator has no effect
^
