Comment(by gellule.xg@…):

 I read a little about _LARGEFILE64_SOURCE there:
 http://www.gnu.org/software/libc/manual/html_mono/libc.html#index-
 g_t_005fLARGEFILE64_005fSOURCE-48
 It looks like setting _LARGEFILE64_SOURCE should make off64_t available.
 Both mplayer and VLC turn it on but never use off64_t. They actually also
 use _FILE_OFFSET_BITS=64 which makes off_t (and related) 64 bits directly.
 To me it looks like both project moved on to a 64bits off_t and should not
 set _LARGEFILE64_SOURCE anymore.
