ffmpeg compilation error on syno-x07

[Olivier Perron]

Hello everybody,

While trying to rebuild ffmpeg for the syno-x07 target, I came across a
compilation error (see log below).
Looks like there is an issue with swscale. I've searched on nslu2 trac and
have find some "fight" with people enabling ffmpeg-swscale-headers.patch
while bzou systematically disables it afterwards.
So I've also tried to re-enable that patch but the compilation fails as well
a few steps after.

I'd appreciate any help on this.

Regards,
Olivier
