Hm, so if it fails to build with GCC 4.6, would you consider that a bug? Because currently it fails to build at Ubuntu 12.04*. Depending on how hard it is to fix, I think it would be nice to be able to build on 12.04 since it is an LTS and will be around for a while (though most users will arguably move on the next LTS version coming next year). 

*It fails at 10.04 too with gcc 4.4, though strictly speaking that's only supported for servers, not desktops at this point so I don't think that would be critical. See https://wiki.ubuntu.com/Releases#Stable for details. 

If you want full output/more details, let me know. (Also should I place it in a bug report, because this comments seems awfully long...)

$ /usr/bin/c++ --version
c++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

I get the following error when attempting to build:
