the git version still can't be linked on windwos (while libav can be linked)
because of it seems do not add bz2 and pthreads' windows .dll to the link list.

if it's recognized bz2 during configure than it'd have to add to the link
params -lbz2.

and if i do not called with --enable-w32threads (and configure find pthreads)
then it'd have to be linked with -lpthreadGC2

same as in libav.
