Yes, this is a bug in dvdnav -- apparently the authors don't know C
any better than they know good library design. ;)

OK, the serious answer now. dvdnav has not been supported by mplayer
for a long time, and will not work even if you fix this bug in dvdnav
header. It never worked much, but if you want to play with it, you'll
either have to revert to a very old version of dvdnav (somewhere
between 1 and 2 years old) or do a lot of coding to fix it. There is a
reason dvdnav is disabled by default rather than autodetected.

BTW, to the devs...should we remove dvdnav entirely from the configure
script so we stop getting bug reports like this?
