I probably simply don't understand above, but are you using 
different pkg_config paths when configuring pthreads and FFmpeg?

Could you post this linking error (with --disable-w32threads)?
That is, you run "make" several times and you always see the 
same error, then you run "make V=1" and post the complete, 
uncut console output of "make V=1" here.
(Please do never post the complete, uncut console output of 
the first run of "make".)

Thank you, Carl Eugen
