It would mean that, in the unlikely event that the user *wants* a comma
operator in a case label, he has to parenthesize the expression.  No different
from the existing situation with function arguments or initializer lists,
except that it's a minor incompatibility with the existing language.

Is there any particular reason this got added to g++ but not gcc?  It would
seem to be equally useful in both.
