Xcode 4.6 compiler default error w/ default templates

When I run Cocos2DX default template, I get two errors in the default unedited project.
My first guess it was a C*+ version issue. I went into the build settings to change C*+ and STDLib to be C11 and libc.
This fixed the issue, but means I would have to change this for every project.

Is it typical this is not set correctly with a default install of XCode 4.6, I thought the defaults were suppose to be C11 and libc.
Is there anyway I can change this default so I don’t have to keep changing this each project?
