+Subject: Allow RUST_TARGET override for detected Rust triplet (fixes musl 
build)
+
+Respect RUST_TARGET from the environment to override Mozilla's
+own triplet detection.
+
+If the variable is unset, the old logic is used.
+
+The issue is that Gentoo supports both, say:
+- x86_64-unknown-linux-musl, and
+- x86-64-gentoo-linux-musl
+
+Our Rust is built to understand
+-gentoo- as a vendor target, but
+our Rust only actually includes
+-unknown-.
+
+Mozilla's configure sees -gentoo-
+in CHOST and that Rust _understands_
+-gentoo- and tries to use it, without
+verifying that we actually have
+-gentoo- installed as a Rust target.
+
+This requires exporting RUST_TARGET
+in the ebuild, possibly like:
+````
+inherit rust-toolchain
+
+src_configure() {
+       [...]
+       export RUST_TARGET=$(rust_abi)

+Subject: [PATCH] Bug 2080242 - Include WidgetUtilsGtk.h for Wayland builds in
+ nsAppShell.cpp. r=stransky,gtk-reviewers,emilio
+
+nsAppShell::IsSessionRestoreSupported() calls IsGnomeDesktopEnvironment()
+under MOZ_WAYLAND, but WidgetUtilsGtk.h, which declares it, was included
+under MOZ_ENABLE_DBUS only. Builds with dbus disabled fail to compile.
+
+Include the header when either is enabled: the dbus code uses
+IsCancelledGError() and the Wayland code uses IsGnomeDesktopEnvironment().
+
