nice fix! A few minor nits:

Please use the customary comment style:

/*
* Comment .....
* ...... goes here:
*/

and since it's multi-line anyway, keep to the 80-col limit too please.

Any reason why it has been moved to a separate line? (either split all
fields or keep them all together)

Please use an enum, not a define in the middle of a struct.

Thanks,
