Hello. This commit https://git.gnome.org/browse/mutter/commit/?h=gnome-3-16&id=55fd05ea588a34564128f9f657084c82eae1cb0b
braks compiling mutter from gnome-3-16 branch.


configure flags are:

./configure --prefix=/usr --sysconfdir=/etc \
      --libexecdir=/usr/lib/mutter \
      --localstatedir=/var --disable-static \
      --disable-schemas-compile --enable-compile-warnings=minimum --disable-wayland

Note: I have to disable wayland otherwise gnome-shell refuses to even start which is fine since nvidia wayland support is going to long take years.


Anyway, error is:
