mpv/subreader.c
uau 8867515f9b Use 0 and 1 instead of FRIBIDI_FALSE and FRIBIDI_TRUE which are no 
longer defined in the current development version of FriBidi. This
reportedly allows compiling MPlayer with the development version which
is needed for Arabic support (some used functions are marked as
deprecated though). Should be safe with older FriBidi versions.
