OK.  I must've confused it with some other problem then.  Something
about labels not allowed right before the closing brace.  But I don't
pay enough attention to these things.

GCC used to allow (not sure if it still does)

label: }

The standard requires a statement after the label even if it's
an empty

	label:
		;
	}

Thanks. Diego.


Cheers
Graham
