[MPlayer-users] HAVE_PTHREAD_CANCEL / FFmpeg a8d8e86

Don't wanna be a bother again. I've had some free time from work. It 
seems MinGW/Windows (mingw.org) now requires HAVE_PTHREAD_CANCEL to be 
defined from that commit in FFmpeg. I compile with pthreads 
(pthreads-w32 2.9.0--the latest 2.9.1 doesn't work with MPlayer nor 
x264) but it doesn't support pthread_cancel (according to FFmpeg's 
configure).

I set HAVE_PTHREAD_CANCEL 0, but again it could be different for another 
environment/pthreads lib.

A lot of other stuff is undefined but `if (!HAVE_PTHREADS_CANCEL)` 
bothers the compiler.
