This is an unnamed structure. Recent versions of GCC
should be able to handle them when setting the
-fplan9-extension flag.

Otherwise, your change is fine, but "hdr" would probably be
a better name than "Biobufhdr". Also, don't forget to update
your code to use b->hdr.fid instead of b->fid, and so on.
