Well... I don't have checked further but since there are
pthread_create() and mplayer is linked against -lpthread, this
-D_THREAD_SAFE should be used. (It was already there for *BSD so I did
not look further)

When you use this flag, it redefines errno on a per-thread basis (among
other things) and defines reentrant functions (blah_r).
If you don't, all your threads will write in one global errno value (for
instance).

Send the suggestions, I'll try and integrate them.
