hmm it's a bit strange, you should take a look at features.h and unistd.h, 
_LARGEFILE_SOURCE does not imply _LARGEFILE_SOURCE64 and vice versa, but 
_FILE_OFFSET_BITS=64 implies things set by both _L... anf _L...64.
IMHO you need only _FILE...=64 or _L... and _L...64. But as mplayersources 
check for _LARGEFILE_SOURCE #define easiest thing would be to additionally 
#define _LARGEFILE_SOURCE64.
But take a look at the system includes yourself there's some strage stuff 
with __REDIRECT checking when using _FIL...=64 stuff.
