Incorrect version reported to MPC

[jedediahg]

Bug report

Just built mpd 0.22.8 and mpc 0.33 from source on fresh install & patched Ubuntu 20.04 "mpc version" returns incorrect mpd version number verified with ls -l /proc/PID/exe that the correct executable is running and no rogue mpd file exists on the system

Expected Behavior

"mpc version" should return "mpd version 0.22.8" (mpd --version reports the correct version)

Actual Behavior

"mpc version" actually returns "mpd version: 0.22.4"

Version

XX@ubuntu2004:~$ mpc version mpd version: 0.22.4

Looks like the error is caused by an error in the meson.build file: version_conf.set_quoted('PROTOCOL_VERSION', '0.22.4')

[MaxKellermann]

Not an error. The version command reports the protocol version, and the protocol hasn't changed since 0.22.4.
