>Description:
In Debian's gcc 3.0.4-7 the -Wswitch option does not work as expected; gcc 2.95 does:
cat >t.c <<EOF
enum {a, b} x = a;
int main()
{
switch (x)
{
case a:
break;
}
return 0;
}
EOF
$ gcc -Wswitch -o t t.c
t.c: In function `main':
t.c:9: warning: enumeration value `b' not handled in switch
$ gcc-3.0 -Wswitch -o t t.c
(No warning message).
