Latest version of Wayland protocol has been built on the radix-1.1 branch (revision 470).
Original Makefile doesn't install man pages correctly and also wayland-1.11.0 sources are not ready for cross compilation because authors use wayland-scanner which was built for target machine on the build machine. It is a most important issue.
Of course we have fixed these issues. See Makefile and corresponded patch.
The work on updating packages on the Platform 1.1 is continued.
