mpv/player/main.c
wm4 e6bea0ec5a Don't include version.h from make options.c 
I find this annoying. It's the reason common/version.c exists at all.

options.c did this for the user agent, which contains the version
number. Because not including version.h means you can't build the user
agent and use it in mp_default_opts anymore, do something rather awkward
in main.c to initialize the default user agent.
