Used the last snapshot of libopenh264 from ​https://github.com/cisco/openh264.

ffmpeg version: N-79222-gc9ad357 (from VERSION file)

[darksab0r]

Yes, the building is broken with openh264 1.6+

I can confirm that this issue is fixed by git commit ​293676c476733e81d7b596736add6cd510eb6960.

Now FFmpeg git master vesion compiles correctly with latest OpenH264 1.6.0.
