C has *always* worked like this.  The body of a switch is a statement
and the switch is a jump.  Here's a really ugly piece of code I wrote
to illustrate this once:
    main(argc)
	{
	    switch (argc)
		if (0) case 1: printf("1\n");
                else if (0) default: printf("not 1\n");
		else printf("impossible\n");
	    exit(0);
	}
"gcc -ansi -pedantic" still likes it!  If you want initialised declarations,
put the switch inside the block instead of the block inside the switch.
A good C compiler ought to print a warning message about initialised
declarations in a switch() body, but that's "quality of implementation".
