--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
GCC now warns by default for this, but the location sucks.
test.c: In function ‘foo’:
test.c:3:3: warning: case label value is less than minimum value for type
switch (c) { case -1: return -1; };
^
It would be nice if it said which type.
Clang says:
test.c:3:21: warning: overflow converting case value to switch condition type
(-1 to 255) [-Wswitch]
switch (c) { case -1: return -1; };
^
