ydr patch for rxgen compatibility

[Derrick J Brashear]

The attached patch causes ydr to accept e.g.
enum foo {
 BAR,
 BAZ
};

and implicitly assign BAR=0, BAZ=1, which is what rxgen does.

It will also pick up the numbering after the last explicitly numbered
entry, deliberately. I didn't look to see what Transarc did in that case.
