Lees, I haven't had a chance to read all the replies but my first thought was;

1). If you end up needing an "emergency" c-sect, you get a spinal or epi anyway
2). If it is a true emergency and they need to give you a GA, they can do a manouver to avoid aspiration (which is one of the big risks with a GA if you've not fasted).

But, my hospital discouraged food during labour. They ordered me a lunch but it was for DH. Fluids were ok but not food. Having said that - food was the last thing on my mind! And I actually threw up when they brought DH lunch! They did ackowledge they couldn't prevent me from eating, but they strongly discouraged it.
