I decided to start from scrath with a new Ubuntu and had a lot of
trouble installing mingw64 with Zeranoe's 3.0.5 script. In the mean time
I have seen revision 5257, 5358 and 5259 of mingw64. With the r5259 I
finally managed to get a working 64-bit environment.


No WINPTHREAD_DBG yet, but the latest ffmpeg and the latest stable x264,
compiled with --enable-debug


PS. For Kyle:
