Well, you may be using another version of gcc, or using different
defaults. I'm using gcc-4.7.2-2.fc17.x86_64 (ie, the gcc currently
shipped in Fedora 17 for x86_64), in what I think to be default
settings.

Note that it's not some local oddity. Looking at the (currently) latest
log for a Fedora build of v3.6-rc7 you'll find an identical warning [0].
Apparently that build was done with gcc-4.7.1-5.fc18.x86_64 [1].
