FWIW, both the C89 and C99 specs refer to it as "case label". 

However, I can't find (anymore?) the place where I thought the C99
standard allowed case labels as targets for goto. Must have dreamed
that... 

Sorry for the confusion,

---------------------------------------------
C89 spec:

3.6.1 Labeled statements

Syntax

          labeled-statement:
                  identifier :  statement
                  case  constant-expression :  statement
                  default :  statement

Constraints

   A case or default label shall appear only in a switch statement.
Further constraints on such labels are discussed under the switch
statement.
