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
