Yeah, none of those are perfect.  I use #1, except I find the default case
often doesn't need the extra braces, so the braces at the same level aren't
as visually obvious.
I guess it's a matter of how important you think it is to have the variables
declared close to where they're used.  It also limits the subsequent scope
of the variable, making it easier to analyze whether or not it's used later,
or e.g. whether perhaps it should have been freed within the local block, etc.

btw, there's a 5th option that is a bit in between:
switch (c) {
        int myvar;
case 'a':
        myvar = somevalue;
        stmt;
}

but I wouldn't recommend it b/c variable initialization on the declaration line
happens in a non-obvious way (or rather, it *doesn't* happen).
