When booting weston-core-image with latest wayland/weston/libinput mouse/touchpad would not work on qemux86, this fixes the issue

The gcc upgrade from the same patchset has been in master for a while but this one is not. I think it should be included: currently mouse does not work in weston when started with "runqemu qemux86 kvm".

In other words, "ping",

Re: [PATCH 1/3] gcc-4.9: Upgrade to 4.9.3

Hi Khem,

This upgrade breaks linux-yocto 3.14 build on qemumips or qemumips64:

In local.conf:
MACHINE = "qemumips"

$ bitbake linux-yocto -ccompile

Then errors:

Thanks.

We have a bugzilla for this issue already, so if anyone else looks into this, make
sure to coordinate with Yang Shi @ Wind River. I sent him that issue.

FWIW, that referenced commit does not port easily .. so this isn't trivial to fix.

Cheers,

Bruce
