This suppresses gcc-4.6.0's warning: -Wmaybe-uninitialized.

PTAL. Can you also fix in upstream webrtc?

Thanks,

LGTM.

LGTM. 
I spent some time on trying to get this warning enabled for us, but I cannot
make it work for my GCC 4.6 compiler. I tried both 4.6.0 and 4.6.2 but both say:
cc1: error: unrecognized command line option ‘-Wmaybe-uninitialized’
Any clue about what may be wrong?

We are using gcc-4.6.0 from the google branch to build Chromium inside
ChromiumOS. The source code can be found here:
http://gcc.gnu.org/viewcvs/branches/google/gcc-4_6-mobile/.

I haven't tried the upstream gcc-4.6.0 but upstream trunk also has this warning.

BTW;

You used the wrong rietveld instance for a webrtc change and this project is not
supported by the commit queue.
