libmythbluray file_open problem?

[Nigel]

OS X build fails like this with 25515 or later:

ld: duplicate symbol _file_open in ../libmythbluray/libmythbluray-0.23.a(navigation.o) and ../libmythbluray/libmythbluray-0.23.a(bluray.o)

Revision 25413 or earlier was fine:

         (undefined [lazy bound]) external _file_open_linux

I'm still trying to work out why this happens.

(In [25532]) libmythbluray: Upstream fix, Mark function pointers file_open and dir_open extern declarations. Possibly fixes #8714?

Sorry, accidentally invoked the post-commit close.

All better now. Thanks Robert!
