If you use an enum you might end up with the value '' if
you enter something invalid, whereas if you use a tinyint(1)
the worst thing you can get is a number outside {0,1}.
If you use a char you'll have all sorts of conversion problems
when using the column in boolena expressions, not to mention
that there are lots of funny values permitted.
I use tinyint(1) in all places where I need a boolean, and
it works fine for me. I've seen rumors about bool being an
alias for tinyint(1), but it's not in the manual and I haven't
tested it.
