It does. You need to enable warnings if you want them:
j@uriah 90% cat > foo.c
int
main(void)
{
int i;
switch (i) {
case 0:
return 0;
case 1:
return 23;
deafult:
return -1;
}
return 0;
}
^D
j@uriah 91% cc -c -Wall foo.c
foo.c: In function `main':
foo.c:13: warning: label `deafult' defined but not used

Well, but you gotta discuss design decisions of gcc with the gcc
folks. We can't/won't do anything but using their contributed code.

Never trust an operating system you don't have sources for. ;-)
