Agreed. Google have done it for their 4.6, Fedora have done it for
4.7 (?), and we've done it for Linaro GCC 4.6 and 4.7.
My concern is that a point release of GCC would stop working against
the latest release of GLIBC.
I'm happy to prepare a backport to GCC 4.6, GCC 4.7, and GLIBC 2.15 so
the next set of point releases will all work with each other. This
would match what the distros are doing.
