Test program:

enum fred
{
        apple,
        orange,
        fruit_1,
        fruit_2,
        fruit_3,
};

int xx()
{
        fred e;
        switch (e) {
        case apple:
                ;
        case orange:
                ;
        case fruit_1 ... fruit_3:
                ;
        }
}

gcc 3.4 correctly accepts this code without warning.
gcc 4.0 (of Mar 17 18:06 UTC) incorrectly generates a warning.

$ /opt/gcc-3.4/bin/g++ -Wswitch -c a1.cpp
$ /opt/gcc-4.0.pre/bin/g++ -Wswitch -c a1.cpp
a1.cpp: In function 'int xx()':
a1.cpp:13: warning: enumeration value 'fruit_2' not handled in switch
a1.cpp:13: warning: enumeration value 'fruit_3' not handled in switch
