struct msdosfsmount so that this file has the same prerequisites as it used to. The new prerequistite was a meta-style bug. It required many style bugs (unsorted includes ...) elsewhere. Formatted prototypes in KNF. Resisted urge to sort all the prototypes, to minimise differences with NetBSD. (NetBSD has reformatted the prototypes but has not sorted them and still uses __P(()).)
