I've just tested with the official 4.6.1 release:
gcc version 4.6.1 (GCC) 

and the 4.6-20110819 snapshot:
gcc version 4.6.2 20110819 (prerelease) (GCC) 

and the tip of the 4.6 branch:
gcc version 4.6.2 20110829 (prerelease) [gcc-4_6-branch revision 178215] (GCC)

and there's no warning or error, so I don't know what the ArchLinux package is
based on. It looks like the 20110819 snapshot with a misleading BASE-VER, but
that shouldn't warn.
