This feature is now natively implemented since patch 9.1.1485: missing Wayland clipboard support

The solutions here are obsolete since then. Wayland clipboard support will continue to mature, there have been quite a few bugfixes since then.

• patch 9.1.1495: Wayland: uses $XDG_SEAT to determine seat

• patch 9.1.1543: Wayland: clipboard appears to not be working

• patch 9.1.1547: Wayland: missing ifdef

• patch 9.1.1561: configure: wayland test can be improved

• patch 9.1.1565: configure: does not consider tiny version for wayland

• patch 9.1.1587: Wayland: timeout not updated before select()

• patch 9.1.1585: Wayland: gvim still needs GVIM_ENABLE_WAYLAND

Regarding last commit - I recommend you remove GVIM_ENABLE_WAYLAND=1 if you have previously enabled that as it is auto-detecting Wayland now.
