switch( someint )
    {
        case 0:
            break;
        case 1:
            break;
        default:
    }

MSVC6 gives an error "syntax error : missing ';' before '}'".
It does not like the last label, be it default: or not, with
no C statement under it.  Testing this on gcc 2.95, it compiles
without any warnings and the -Wall option specified.

Which makes me wonder what does the standard say on this.  Are
"empty last labels" prohibited?

P.S.  I know there's no need for an "empty last label", such
as in the example above, because we'll exit the switch anyways.
The code above is just an example.  I actually found this by
commenting out all the code below the last case in switch().

   Lately I've had to use Microsoft's Visual C++, and I just
   noticed this.  In the following switch statement:

       switch( someint )
       {
           case 0:
               break;
           case 1:
               break;
           default:
       }

   MSVC6 gives an error "syntax error : missing ';' before '}'".
   It does not like the last label, be it default: or not, with
   no C statement under it.

According to the Standard, every label must be followed by a
statement, even if that's just the empty statement ';'.

   Testing this on gcc 2.95, it compiles without any warnings and the
   -Wall option specified.

If you specify -ansi -pedantic, gcc 2.95 (and earlier versions) will
complain, too.

   Which makes me wonder what does the standard say on this.  Are
   "empty last labels" prohibited?

Yes.
