--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
IIRC one of either you or Marek fixed this for gcc8:
$ /usr/local/bin/gcc -c -S -Wall 79204.c
79204.c:4:11: warning: overflow in conversion from ‘int’ to ‘T {aka signed
char}’ changes value from ‘28782’ to ‘110’ [-Woverflow]
#define N (X * Y)
^
79204.c:6:7: note: in expansion of macro ‘N’
T x = N;
