$ ed test.c
main ()
{
	switch (getchar ()) {
		default:
			puts ("not a zero");
			break;
		case '0':
			puts ("was a zero");
			exit (0);
	}
	goto default;
}
$ cc -c test.c
"test.c", line 11: syntax error

That's what happens if you goto default.  The syntax for a goto is

	<goto_statement> ::= `goto' <identifier> `;'

The word `default' is not an identifier, it is a reserved word.
