[FFmpeg-user] Problem building with libx265

[Andrew Sinclair]

Hi,

This used to build for me OK but for some reason it no longer builds with
./configure --enable-libx265

I am using latest git pull from today from both repos but I think this may
be specific to my machine for reasons I can't work out. So if anyone has
pointers please let me know? Details below

Error from configure:
